AN INTERPRETATION FOR KINETICS OF MARTENSITIC TRANSFORMATIONS

Martensitic transformations have been classified into two groups, athermal and isothermal ones, from the

view point of kinetics. This classification may not be intrinsic because an isothermal transformation changes to an

athermal one and vice versa by the application of external fields such as magnetic field and hydrostatic pressure [1].

This finding suggests that any martensitic transformation is intrinsically an isothermal one, but appears to be an

athermal one in many cases because of undetectably short incubation time.

In this presentation, we will demonstrate several examples of isothermal nature observed in alloys which are

so far considered to exhibit an athermal transformation. That is, we will show that thermoelastic transformations in

some shape memory alloys (SMAs), such as Cu-Al-Ni and Ni-Co-Mn-In alloys, proceed isothermally after some

incubation time although each alloy has a so-called martensitic transformation start temperature (Ms) when it is

cooled with a constant rate. In addition, we will demonstrate that the first order magnetic transition of FeRh also

show clear time dependence. These results are explained by a statistical thermodynamic model derived by the

authors.

ISOTHERMAL DIFFUSIONLESS MARTENSITIC TRANSFORMATIONS IN SHAPE MEMORY

ALLOYS

Recent experimental results indicate that a number of diffusionless martensitic transformations (MT) in

classical shape memory alloys (SMA), like binary and ternary ones belonging to the Ni-Ti system, which were

thought to be athermal actually demonstrate isothermal behaviour [1]. Similar features are found in metamagnetic

SMA from the Ni-Mn-X family [2]. We present and analyze here experimental data on the kinetics of isothermal

MT in conventional Ni-Ti and Ni-Ti-X (X=Fe, Cu) as well as in metamagnetic Ni-Mn-In and Ni-Mn-In-Co alloys.

We found similar essential details in kinetics of isothermal diffusionless MTs in metamagnetic and

conventional SMA. First, isothermal effects can be observed during both direct and reverse MTs and are restricted

to the temperature range between the start and finish of the MT as detected by calorimetry. The intensity of

isothermal effects is found to be essentially proportional to the heat flow. Over the major part of the MT range,

isothermal effects follow a logarithmic kinetics, pointing to the existence of an energy landscape with a broad

distribution of activation energies. Deviations from the logarithmic kinetics are observed close to the finish

temperature of the MT and can be attributed to the appearance of a certain “incubation time”. We show that a

correlation exists between the width of the transformation range and athermal or isothermal nature of the

diffusionless MT. This fact, together with proportionality between the MT rate in a continuous cycle and the

intensity of isothermal effects and also observations of the isothermal reverse MT, allows us to attribute isothermal

features of diffusionless MTs to the thermally activated motion of interphase boundaries. The appearance of the

“incubation time” in this framework can be interpreted as a depletion of the energy landscape with low activation

energy configurations close to the finish temperature of the MT. Possible role of thermally activated nucleation

events is discussed.

Copper based shape memory alloys (SMA) are being developed as an alternative to the classical Ti-Ni SMA,

for functional applications at low and medium temperatures, specially in between 100ºC and 200ºC, which is an

important temperature range for many applications in several industrial sectors such as aeronautic, aerospace and

automotive.

The main drawback of Cu-based SMA is their intrinsic brittleness in polycrystalline state, being at present

responsible of a lack of commercial products. However research performed along the last decades has allowed new

technological solutions, from powder metallurgy to single crystal growth, offering new performances of Cu-based

SMA.

In the present lecture we will overview the last developments in Cu-SMA, in particular from the families of

Cu-Al-Ni and Cu-Al-Be as well as more complex systems, outlining the main advantages that can be exploited from

each family, in comparison with Ti-Ni SMA. Superelasticity, shape memory and damping properties will be

overviewed.

Another cutting-edge field for SMA is the research of their behavior at micro and nano-scale for applications

as sensors and actuators in Micro Electromechanical Systems (MEMS). Recent works in this field [1,2] show that

Cu-Al-Ni SMA exhibit very good superelastic and shape memory effects at micro and nano-scale, attracting a

renewed interest on this system. We will also overview in the present lecture the behavior of Cu-based SMA at

micro and nano-scale discussing the potentiality of such systems for practical applications.

The magnetic shape-memory effect was first reported in 1996 by the group of Bob O‟Handley at MIT. They

proved that large deformations can be induced by application of a moderated magnetic field in the martensitic phase

of a Ni2MnGa ferromagnetic Heusler alloy. At present many other materials displaying similar behaviour have been

developed. In general, magnetic shape-memory properties refer to the ability of certain materials to show strong

response in strain to an applied magnetic field. This strain is caused by either field inducing the martensitic

transition or rearranging martensitic variants. In the first case a superelastic effect is possible, while in the second

the system is able to show the shape-memory effect. The complex behavior displayed by these materials is mainly a

consequence of a strong interplay between magnetism and structure which is driven by a martensitic transition. This

interplay is the source of many other observed effects such as giant magneto-resistance, exhange bias and

magnetocaloric effects. The investigation of magnetic shape-memory materials is an expanding field of research

involving great richness of basic physics together with technologically interesting possibilities for applications of

their multifunctional behavior. In my lecture, I will overview the present state of the art of the field focusing

particularly on the nature of the magneto-structural interplay, phase diagrams and mechanical, magnetic and thermal

properties of this class of materials. Finally, I will discuss some present challenges and outline future perspectives in

the field.

NANO- AND MICROCRYSTAL STRUCTURE INVESTIGATIONS OF INTERFACES, GRADIENT AND

STRAIN FIELDS IN MARTENSITIC MATERIALS BY VARIOUS EM TECHNIQUES

Optimization of materials for dedicated applications through, for example, thermo-mechanical treatment

typically yields micro- and/or nanostructures that need to be investigated with high-resolution instrumentation in

order to elucidate and understand the chemical constituents and their exact atomic configurations inside the different

components or, often more importantly, at and around the interfaces between these components.

Our recent work has focused on ternary alloys based on the omnipresent Ni-Ti system, aiming for an adapted

hysteresis towards low values, following the 2 = 1 concept in which a perfectly coherent untwinned martensite is

formed, and on the Ni-Ti-Nb system in which large amounts of incoherent nano-precipitates are seen to hinder the

transformation resulting in a slight increase of hysteresis. Samples of different compositions and with different heat

treatments are investigated by DSC and various TEM and FIB/SEM methods to elucidate the relation between nano-

and microstructure and the martensitic transformation behaviour.

In single crystal Co-Al-Ni samples ‟ L12 precipitates can form varying from large interdendritic shapes to

smaller sheet-like ones with internal twins, both revealing the K-S orientation relationship with the austenite matrix.

The occurrence of the internal twin clearly affects the outer shape of the precipitate, including facets and re-entrant

grooves leading to fast growth along particular directions. When the precipitate is embedded inside a martensite

matrix, a sandwiched retained austenite region is often observed between the precipitate and twinned martensite due

to a strong change in local composition resulting from the Co-depletion and Al-enrichment of the matrix near to the

precipitate.

In order to better understand the concept of strain glass, binary Ni-Ti samples of different compositions have

been investigated by quantitative high-resolution Cs-corrected TEM. First results indicate that small pockets of

around 3 nm in diameter reveal strained lattice in 51.7 at.%Ni and that the lattice displacements measured at room

temperature in the 51.7 at.%Ni sample are about twice as large as those measured in the 50.8 at.% sample.

In this work, TNZ: Ti-(18...22)Nb-(5...6)Zr and TNT: Ti-(19.5…21)Nb-(6.5…7)Ta (at%) ingots were

manufactured by vacuum and argon arc melting. Both alloys were cold-rolled (CR) from 30 to 85% of thickness

reduction, annealed in the 450 to 900oC temperature range (10‟-5h) and aged at 300

oC (15‟-3h). Selected TNZ

ingots were atomized using Rotating Electrode Process (REP) to produce 100 micron size powders.

Both TNZ and TNT alloys subjected to CR of 30% and post-deformation annealing (TNZ: 600oC, 30‟; TNT:

500oC, 1h) possessed polygonized dislocation substructure (average subgrain size 100 nm) and manifested

perfectly superelastic behavior during RT cyclic testing. Young‟s modulus of TNZ alloy was higher, while ultimate

tensile strength (UTS) was lower than that of TNT alloy: 40 GPa > 30 GPa, while 400 MPa < 500 MPa. After aging

treatment, Young‟s modulus of both alloys increased and reached 55 GPa, while their mechanical behavior was

impacted differently: it was detrimental for TNZ and beneficial for TNT. After 300oC, 1h aging, TNZ behavior

become brittle because of a decreased difference between UTS and transformation yield stress (620-550 MPa),

whereas superelasticity of TNT was improved (UTS-trans.stress= 550 MPa-200 MPa). The different influence of

aging on the mechanical behavior of both alloys is explained by the specificity of , and ” phases formed during

aging and their effect on transformation temperatures.

TNZ powder was used to manufacture open-cell foam of 45% porosity (cell size from 150 to 550 microns)

using a polymer-based foaming agent. After sintering, this foam was thermally treated at the same temperature as

the bulk alloy (600oC) and its tensile, compressive and flexural behaviors were compared with those of Ti-CP foam

of the same porosity. For TNZ foams, the highest apparent Young‟s modulus was observed with the as-sintered

material (8-12 GPa) and the lowest was observed after annealing at 600oC (5-7 GPa). As for Ti-CP foams, their

Young‟s modulus remained stable regardless of the heat treatment conditions: it varied between 10 and 14 GPa

depending on the deformation mode.

The main fields of the practical application of TiNi- based alloys with shape memory and superelasticity

effects in engineering and medicine have been identified in the past decade. There are temperature-sensitive

elements for the actuators, damping devices, fasteners, medical instruments and implants (correctors, clamps, stents)

for trauma, spine, dentistry, soft tissues and vessels. The development of science and high technologies to produce

semi-finished (thin-walled tubes, tapes and thin wire), as well as processing methods (laser cutting and welding) of

TiNi-based SMA over the last 10 years contributed to the creation and implementation into clinical practice more

complicated and advanced devices based on solid and porous shape-memory materials, as well as tissue (metal-

textiles) and knitted (metal-jersey) implants, which led to the development of reconstructive surgery.

The accumulated experience and long-term effects on the biocompatibility of installed implants permanently

expands the geography of production (for example, in Russia, see

Fig. 1). The annual volume of supplies of different types of implants to Europe and Asia only from Russia amounts

tens of thousands of articles.

This review examines the conditions which determine the mechanical and chemical biocompatibility of implants.

Development and use of implants, devices and instruments for cardiovascular surgery, endoscopy and laparoscopy

in urology and gastroenterology, in other areas of medicine are discussed. Special attention is paid to the description

of technique of new devices creation and methods of their medical applications. Various examples of their practical

application are presented.

The Ti-Ni alloys have been successfully applied as biomaterials such as orthodontic arch wires, guide wires

and stents in addition to many engineering applications. However, it has been pointed out that pure Ni is a toxic

element and causes Ni-hypersensitivity. Although the Ti-Ni alloys are considered as safe in the human body based

on experience and scientific consideration, in order to solve the psychological problem on the risk of Ni-

hypersensitivity, Ni-free -Ti SM and SE alloys have been recently developed. The Ni-free Ti-based alloys have

not been used for applications yet, but will be used for medical applications in the near future.

In this presentation, the history of the development of Ti-based alloys including Ti-Ni and -Ti alloys is

reviewed, then the basic characteristics such as the martensitic transformation and shape memory properties of the

-Ti alloys are explained in addition to recent reserch results of these alloys.

The microstructure of the martensite in shape memory alloys is characterized by the combination of multiple

habit plane variants (HPVs) to minimize the elastic strain energy upon transformation, which is so-called self-

accommodation (SA). In the present study, the SA morphology of the B19' martensite in Ti-Ni alloys is

systematically investigated by scanning electron microscopy (SEM), conventional transmission electron microscopy

(CTEM) and scanning transmission electron microscopy (STEM). There are twelve pairs of the minimum SA unit

consisting of two HPVs with V-shaped morphology connected to a {-1-11}B19' Type-I variant accommodation twin.

It is found that an ideal SA morphology consists of three V-shaped units, i.e., a total of six HPVs, clustered around

one of the {111}B2 traces with hexagonal shape. Triangular and rhombic SA morphologies are also observed. It is

revealed that there are four kinds of characteristic HPVs interface to complete the SA morphologies. The variant

selection rule and the number of possible HPV combinations in each of these self-accommodation morphologies are

discussed. Three dimensional SA morphologies are also investigated by the novel SEM technique. The proposed

models are rationalized by the phenomenological theory of martensite crystallography and the geometrically

nonlinear theory, which will be presented in Part II of this series.

The competition among the invariant plane (IP) condition at the habit plane, the twin orientation relation (OR) and

the kinematic compatibility (KC) at the junction plane (JP) of self-accommodated B19‟ martensite in Ti-Ni was

investigated by means of geometrically nonlinear theory in order to understand the habit plane variant (HPV)

clusters presented in Part I of this work. As the IP condition cannot be satisfied simultaneously with KC, an

additional rotation Q is necessary to form compatible JPs for all HPV pairs; Q ≠ I, where I is identity matrix. The

rotation J necessary to form the exact twin OR between the major correspondence variants (CVs) in each HPV was

also examined. There is no twin OR between the major CVs in HPVs when the IP condition at the habit plane is

satisfied (J ≠ I). These results mean that fully compatible HPV cluster with a JP keeping twin OR is impossible in

Ti-Ni. However, there exist special pairs of HPVs that satisfy the twin OR and KC conditions at the JP

simultaneously by identical rotation (Q = J). The preferentially observed HPV cluster that is coupling of two HPVs

was not the cluster with the smallest Q but the one satisfying Q = J with a {-1 -1 1}B19‟ type I twin at JP. These

results indicate that both Q and J are crucial to understanding the various HPV clusters in realistic transformations.

The geometry of JP in the HPV clusters that are formed by three, four or six HPVs is also discussed.

It is well-know that TiNi intermetallic alloy is covered by a thin passive layer of TiO2 that provides the

biocompatibility of the alloy. In order to understand at the microscopic level the formation of the alloy-oxide

interface, it is necessary to study the interaction of oxygen with the alloy surface as initial stage of this process. In

the present work, we investigated the oxygen adsorption on TiNi(110) surface in dependence on the oxygen

concentration, which allows us to suggest a model for the TiNi/TiO2 interface. The calculations of atomic and

electronic structure of clean TiNi (110) surface and with adsorbate as well as alloy-oxide interface were carried out

by using ab-initio method within density functional theory. It was shown that, the pseudo threefold-coordinated

hollow site is preferable for the oxygen adsorption on the alloy surface. During relaxation, the oxygen atom shifts to

this hollow position, inside a triangle formed by two Ti atoms and one Ni atom, from the initial Ti-Ni bridge

position. The interaction of alloy surface with oxygen leads to the displacement of Ti surface atoms towards the

vacuum whereas Ni atoms shift oppositely into the bulk. It is shown that the breaking of Ti-Ni bonds is observed

upon increasing O concentration. The formation of the first oxide layers leads to depletion of Ti atoms at the

interface, and as a consequence, to the formation of the Ni-rich interface. Two models of TiNi/TiO2 interface were

considered. The analysis of electronic characteristics at the interface, surface and bulk were performed. The

formation energies (Ef) of Ni-antisite defect, i.e., the Ni atom replacing the Ti one, in TiO and TiO2 as well as

TiNi/TiO2 interface were calculated. It was shown the Ef of Ni antisites is lower in TiO (3.05 eV) in comparison

with TiO2 (7.51 eV). The influence of oxygen vacancies on the defect formation energies was considered as well.

Our results reveal that Ef of Ti-Ni swap defect is lower that that of Ni antisites at the alloy-oxide interface. The

mechanism of the Ni atom segregation inside oxide layers is discussed. The increase of the formation energies of

defects in the fully stabilized TiO2 layers indicates the increase of diffusion barriers of Ni in TiO2 as compared to

TiOx, which results in the decrease of Ni segregation.

Today, for maintenance of certain properties on a surface of metal materials methods of ion-plasma

magnetron deposition are widely used. A results of experimental study of structural conditions in layers which are

formed in the coatings, intermediate zones and in the subsurface layers of a substrate material contacting to a

coating are a fundamental basis for creation by these methods of coatings with high parameters of plasticity and

durability, corrosion resistivity, having high adhesive properties.

The purpose of this report – to present the results of the investigation of gradient structures that were formed

in the subsurface area of the Si-coated TiNi alloy. The Silicon coatings by the thickness of 100–150 nm on the TiNi

samples surface were formed by the ion-plasma magnetron deposition method. One part of the Silicon-coated TiNi

samples was surface modified using the high dozen ion implantation regime. The study of the synthesized

subsurface gradient structure was made using SEM EBSD and X-rays diffraction techniques.

It was found that after deposition of the Si-coatings on the TiNi sample surface in all samples the subsurface

area directly under the coating was splitted into layers differing by their substructure. Moreover, an intermediate

layer by thickness in 2-3 grains of the basic B2-phase located on some excision from a surface was observed. In this

layer, except B2 phase (the main phase of the TiNi substrate material) there are both R and B19‟ martensitic phases

induced due to internal stress. After disappearance these phases the internal border is formed.

We conclude that the typical changing of subsurface structure can be described within the limits of the

multilevel approach. Level I (macroscopic) is shown at construction of the Crystal Orientation maps. Level II

(mezoscopic) is shown in the form of presence disorientations in separate grains of phase B2 which can be taped

using construction of Cubic Rodrigues-Frank orientation maps. Level III (microscopic) is identified by the analysis

a crystalline lattice disorientations using Euler angle coloring maps.
