Introduction
The word “cryogenic” originates from the Greek word “krys” which means cold. Heat treatment applied
at unconventionally low temperatures is referred to as cryogenic (Akincioğlu et al., 2015). This
treatment has been given different names in different sources such as cryo, deep cryogenic treatment,
cryogenics, cryo processing are some of the sources. Cryogenic treatment began to be used in the late
sixteenth century to enhance the mechanical properties of materials.
Generally, the concept of cryogenics denotes the science that deals with very low temperatures.
However, this has not been particularly specified and could be indicated to the temperatures lesser than
120 K which is the air’s boiling point (Timmerhaus & Reed, 2007) or is 100 K (Karassik et al., 2008).
Normally typical cryogens which is in the mode of liquid gases and could be called as liquid nitrogen
(LN2), helium (LHe), oxygen, ethane, methane and argon. Yet, in machining, at times temperatures more
than100 K would also be stated by some authors as cryogenics, for instance, cryogenic machining that
uses solid carbon dioxide and/or liquid (Machai & Biermann, 2011; Abele & Schramm, 2008; De Chiffre
et al., 2007) and even chilled air at very low temperatures (Yalcin et al., 2009; Tsai & Hocheng, 1998).
In reality, there are major differences between the treatments performed at different temperatures and
with different cycles. Consider the case of the treatments performed at -84 °C and at -196 °C. The
improvement in wear resistance is less in the former than the later. Whatever may be the scope of
treatment, the purpose remains the same, i.e. to increase the hardness of surface, wear resistance, and
toughness of the cutting tool. It has been reported that cryogenic treatment assists in increasing the
wear resistance of steels while its implementation through cutting tools. This being the reason;
numerous studies have been conducted to evaluate the resistance power and its longevity of cutting
tools treated with cryogenic materials. For instance, the study by Mohan Lal et al. (XX) where they
examined the improvement in wear resistance and the significance of treatment parameters in the
various tool and died materials. It was identified that cryogenic treatment induces approximately 110%
improvement in tool life.
Scientific studies have revealed that cryogenic treatment applied to cutting tools improves mechanical
properties such as workpiece surface roughness, homogeneous carbide distribution, hardness, and
toughness. However, sufficient information about the application of cryogenic treatment to cutting tools
lacks especially with specific reference to deep cryogenic treatment. In addition, the cryogenic
processing application system has a high initial investment cost, which is a disadvantage in terms of the
applicability of the process. Various gases such as helium, oxygen, nitrogen, and neon are used for
cryogenic treatment [74, 79, and 80]. Nitrogen constitutes a significant portion (78.03 %) of the
atmosphere, and liquid nitrogen, the most commonly used gas in cryogenic treatment applications
(Kalia, 2010; Firouzdor et al., 2008; Thakur et al., 2008).
Although there is sufficient literature available, still it is not clear whether deep cryogenic treatment
enhances the wear resistance of some specific steels as studies conducted elsewhere significantly
focused on general cryogenic treatment. Therefore, this review aimed to explore the studies conducted
on deep cryogenic treatment and identify the gap for the future studies. The paper is structured as

follows: section 2 introduces the concept of cryogenic treatment and deep cryogenic treatment while
this is followed by the cryogenic system and types of cooling system (Section 3). Section 4 critically
reviews the previous studies conducted elsewhere on deep cryogenic treatment. Finally, the section
summarizes the findings and conclude the paper.
Cryogenic Treatment
The liquid nitrogen that is generated from the nitrogen plant is kept in storage vessels. Then, transfer
lines are used to direct the same to a closed vacuum evacuated chamber that is known as cryogenic
freezer with the help of a nozzle. The supply of liquid nitrogen into the cryo-freezer is subjected to
operation with the help of solenoid valves. The gradual takes place inside the chamber at a rate of 2º C
/min from the room temperature to a temperature of -196º C. Once it attains the sub-zero temperature,
specimens are transferred to the nitrogen chamber or soaking chamber, in which they are stored for 24
hours while supplying liquid nitrogen continuously. There are three significant elements of the cryogenic
treatment process, as obtained from the research conducted in the Mechanical Engineering Department
at Louisiana Tech University. Those elements are a very slow cool down from ambient temperature to
cryo generic temperature, a long soak at cryogenic temperatures, and a triple heat temper after the
cryogenic treatment.
CRYOGENIC SYSTEM
A cryogenic system is an equipment that allows cooling temperature, (i.e. cooling and heating rate),
specifically cooling in the cryogenic range in a chamber using cryogenic fluid like liquid helium or
nitrogen. During The sixties, Cryogenic treatment was done by direct immersion into liquid nitrogen,
which produced a catastrophic result of cracking the components. But later, the cryogenic treatment
system developed by Ed Busch (Cryo-Tech, Detroit, MI) in the late 1960‘s and later improved by Peter
Paulin with a temperature feedback control on cooling and heating rate which, prevented sudden
temperature changes and led to the development of efficient CT process.
Deep cryogenic treatment is an economical permanent treatment that impacts the mechanical aspects
of the steel components. The percentage of retained austenite contained by the conventional treatment
of steel is lessened by the process of deep cryogenic treatment. The elimination of retained austenite
and the cleansing of carbide particles are the main causes of the wear resistance enhancement. By using
deep cryogenic treatment method, the fragments are slowly cooled from room temperature to _196_C
and are soaked for around 12 to 24 hours at _196_C, and later reheated slowly again to the room
temperature continued by tempering. Charles and Arunachalam (2003) indicated that the cryogenic
treatment is a homogenous process and needs to be conducted only once that offers major significance
in the productive and functional life of steel components such as gears, engines, machine parts, brake
rotors, and transmission to gun barrels, machine tools.

TYPES OF COOLING SYSTEM
There are three types of cryogenic cooling systems that are commonly used Gradual Immersion, Direct
Nebulization, and Heat Exchanger. Out of these three processes, the concept of third procedure of
cooling system is generally used widely. Liquid nitrogen is allowed to flow from the storage tank through
inlet pipe and allowed to enter into the cryogenic chamber (also called as Cryoprocessor-box).
Temperature is controlled through computer programming software Delta TTM, and desired cooling
rate can be set. The cooling effect is provided by LIN to the sample, but no direct contact is allowed,
among them. A fan is used for uniform distribution of temperature inside the chamber. After reaching
the temperature set by programmer thermocouple sends a signal to the system controller, through a
feedback mechanism, and hence, temperature controller regulates the flow of LIN in the chamber and
stop further cooling. The LIN gets converted and leaves the system as nitrogen gas (Dhar et al., 2001).
PREVIOUS WORK
Several studies have been conducted previously on deep cryogenic treatment
Hong and Ding (2001) identifying the cooling approach for most effectively and economically using
cryogenic machining. This study evaluated cutting temperatures obtained under various cooling
conditions where study applied liquid nitrogen (LN2) to cut Ti-6Al-4V, a difficult-to-machine. Dhar et al.
(2002) performed a study by applying the LN2 jet while turning of AISI 4140 steel in the cutting zone and
found higher surface roughness, limited tool wear and high dimension of accuracy when compared to
dry and wet machining. Stewart (2004) conducted cryogenic treatment into C2 tungsten carbide (WC-6%
Co) inserts and correlated to untreated carbide inserts in a medium density fibreboard (MDF). Reddy et
al. (2008) determined the impact of deep cryogenic treatment over the chemical vapor deposition (CVD)
coated over carbide ISO P-30 inserts in the machining process of C45 steel. Arrazola et al. (2009)
evaluated a tool wear mechanisms when machining Ti555.3. Vadivel and Rudramoorthy (2009) in the
turning of nodular cast iron evaluated the microstructure of cryogenically treated (TiCN+A12O3) and the
untreated inserts and found that the treated and coated carbide inserts had better significance that
untreated (UT) carbide tools.
Studies on Titanium
This section reviews the specific studies on the effect of deep cryogenic treatment on Titanium.
Gill et al. (2011) enhanced the effects of shallow and deep cryo-treated carbide tools in C-65 steel
turning. Based on preliminary turning tests, the cutting speed was varied in four increments: 110,
130, 150, and 180 m/min. All the cutting tests were performed at a feed rate of 0.1 mm/rev and
depth of cut of 1 mm. The cryogenic treatment appeared to be effective in reducing surface roughness
for relatively longer machining times. Cryogenic treatment causes crystal structure changes in both the

hard and soft binder phase of tungsten carbide which, along with the precipitation of phase carbides,
may have been responsible for the enhanced cutting life of the cutting inserts.
Armendia et al. (2012) examined that single-point tool life analysis and a Orthogonal cutting force
measurements to evaluate the response to heat treatment by machining on three titanium alloys
namely Ti6246, Ti-5Al-4V-0.6Mo-0.4Fe (TIMETAL1 54M) and Ti6Al4V. The TIMETAL154M indicated
higher performance than the regular Ti6A14V of a tool life of 15 minutes with a 20% maximized
allowable cutting speed. The Ti6246 alloy indicated the highest cutting forces and higher tool wear rates
in various heat treatment settings due to its durable mechanical properties. A recently developed allow
with identical mechanical properties of Ti6A14V called the TIMETAL1 54M alloy, indicated lower wear
rates. In machining of alloys, there had been microstructural variations as an effect of heat treatment.
The b annealed samples of the When TIMETAL1, and Ti6A14V 54M alloys were taken and b annealed,
with a fine lamellar microstructure, indicated considerable high cutting forces and short tool life.
Whereas the other heat treatments indicated no major impact on the machinery behavior of the
evaluated alloys as it produced no microstructural developments. The Ti6246 alloy indicated shorter tool
life and high cutting force measurements in the tested body. The test outcomes indicated better
mechanical properties of the alloy when correlated to TIMETAL154M and Ti6A14V alloy.
Dhananchezian et al. (2011) examined the effect of LN2 cooling while turning of AISI 304 stainless steel
using modified tungsten carbide tool inserts. The effect of liquid nitrogen as a coolant applied through
holes made on the rake and flank surfaces of the PVD TiAlN coated tungsten carbide turning tool inserts
of ISO CNMG 120412 MP–KC5010 on the turning of AISI 304 stainless steel is studied. The influence of
cryogenic cooling on the cutting temperature, cutting force, surface roughness, and tool wear has been
compared with those of wet machining. It is observed that in the cryogenic cooling method, the cutting
temperature was reduced by 44–51%, the cutting force was decreased to a maximum of 16%, and the
surface roughness was reduced by 22–34% over that of wet machining. Cryogenic cooling using liquid
nitrogen reduced tool wear through the control of temperature-dependant wear mechanisms.
Senthilkumar and Rajendran (2012) illustrated a study on L27 Taguchi orthogonal design with the
parameters of deep cryogenic treatment to attain a minimum wear loss of 4140 steel. The four
identified process parameters included for the optimization study were hardening temperature (A),
soaking period (B), tempering temperature (C), and tempering period (D). The communications among
these factors are also determined. In the deep cryogenic treatment method the most important factor
was the hardening temperature at a percentage of 17.34% at 888 C. It was also determined that
interactions between the hardening temperature vs. tempering temperature (AxC) and soaking period
(2.32%) vs. tempering period (2.35%) (BxD) has been more vital than any other factors.
Ravi and Kumar (2012) organized an investigation on the impact of cryogenic cooling using liquid
nitrogen (LN2) jet in the performance of milling in hardened AISI D3 tool steel using TiN-coated carbide
inserts. The test was conducted at a stable speed of 125 m/min at three various feed rates at the range
of 0.01 to 0.02 mm/tooth. In the process of LN2 machining. The cutting temperature was limited to 43-
48% and 22-39% in dry and wet machining. The results show that machining with LN2 lowers cutting
temperature, tool flank wear, surface roughness and cutting forces as compared with dry and wet

machining. With LN2 cooling, it has been found that the cutting temperature was reduced by 57–60%
and 37–42%; the tool flank wear was reduced by 29–34% and 10–12%; the surface roughness was
decreased by 33–40% and 25–29% compared to dry and wet machining. The cutting forces also
decreased moderately compared to dry and wet machining. This can be attributed to the fact that LN2
machining provides better cooling and lubrication through a substantial reduction in the cutting zone
temperature.
Reddy and Ghosh (2014) explores the negative side of cryo technology in a case study, where hardened
bearing steel (AISI 52100) was ground by an alumina wheel with chilled N2 in both gas and liquid (LN2)
jet form. Elemental analysis of the sample was carried using Optical Mission Spectroscope (OES) -196 is
the temperature. The machine tool used is Reciprocating surface grinder. It was observed that the
ground specimen suffered a significant dimensional deviation with the liquid jet with respect to dry and
soluble oil environment. In a similar fashion, microhardness of workpiece notably was changed and so
was the deterioration of surface finish. On the contrary, G-ratio was found to be remarkably improved,
which is in line with information about the available literature. The extent of those adverse effects could
be controlled by using chilled N2 gas instead of LN2 jet however with a compromise on G-ratio.
In this Gill et al. (2011) discussed the enhanced the tool life in the interrupted machine under the
cooling conditions. Armendia et al. (2012) examined about the single point analysis of the orthogonal
cutting. Senthilkumar and Rajendran (2012) studies on L27 Taguchi orthogonal design with the
parameters of deep cryogenic treatment to attain a minimum wear loss. Dhananchezian et al. (2011)
also studied about the LN2 cooling but by using the tool AISI 304. Ravi and Kumar (2012) impact of
cryogenic cooling using liquid nitrogen (LN2) jet in the performance of milling in hardened AISI D3 tool
steel using TiN-coated carbide inserts. Reddy and Ghosh (2014) explores the negative side of cryo
technology in a case study, where hardened bearing steel (AISI 52100) was ground by an alumina wheel
with chilled N2 in both gas and liquid (LN2)
Studies of Wear resistant
This section reviews the studies on deep cryogenic treatment on wear resistant. Kaushal et al. (2015)
evaluated about Micro- structure and Hardness, after Cryogenic treatment comparison is also made
with untreated test specimen. The study adopted temperature of about – 196 by using the tool steel
AISI- D2. The study findings revealed that hardness increased after cryogenic treatment in comparison
with untreated also change in the micro- structure was observed due to phase transition from austenite
to martensite which also altered the various properties of tool AISI-D2 steel.
Jandová et al. (2015) investigated the impact of a deep cryogenic treatment on the wear resistance and
microstructure of the X37CrMoV5-1 (H11) hot-work steel. The wear resistance was measured at 400 °C
using the pin-on-disc method with a rotary tribometer. The microstructure of the steel was examined
using light and transmission electron microscopes. The study findings revealed that a microstructural
observation in a light microscope did not reveal any substantial differences between the specimens
hardened in the conventional manner and the specimens after a deep cryogenic treatment. On the

other hand, the analysis of specimens upon deep cryogenic treatment by means of transmission
electron microscopy found two types of substructure, which are likely to facilitate the precipitation of
fine carbides during the final tempering of the steel. At this point, the impact of longer holding times at
the deep cryogenic temperature on this substructure has not been analyzed. The cause of the decline in
the wear resistance with extended holding times cannot thus be determined.
Ather and Sonawane (2015) aimed to reveal the enhancement of wear resistance of AISI D3 Tool Steel
by Cryogenic Treatment. In the experimentation process, samples of AISI D3 tool steel were taken in
batches out of which some samples were treated with conventional heat treatment (QT) whereas other
were cryogenically treated (QCT) at 77 K for a period of 24 hrs. The study findings revealed that there is
an increase in wear resistance of AISI D3 material after performing the cryogenic treatment. Yet, this
increase varied from few percent too few hundred percentage. Therefore depending upon the load
conditions, cryogenic treatment should carry out or not.
In this Jandová et al. (2015) investigated procedure and the results of exploring the impact of a deep
cryogenic treatment on the wear resistance and microstructure of the X37CrMoV5-1.

From the review, it is found that cryogenic is applied to wear resistant, titanium, stainless steel and for
metallurgical analysis. In future, the cryogenic can be applied to other components like gears, shaft and
springs to improve their performance. In addition, it is observed that only a few reviews were made by
considering CVD, OEM. The future work can also be done by considering tungsten carbide, HSS, PVD,
