Databases of Baikov Institute on properties of inorganic materials and substances

ABSTRACT
The principles of organization of the databases (DBs) on properties of inorganic substances and materials of A.A.Baikov Institute of Metallurgy and Materials Science (IMET): the DB on the properties of inorganic compounds “Phases”, the DB on phase diagrams of systems with semiconducting phases “Diagram”, the DB on properties of acousto-optical, electro-optical and nonlinear-optical substances “Crystal”, the DB on band gaps of inorganic compounds “Bandgap” and the DB on properties of chemical elements “Elements” are considered. The peculiarities of these DBs are: Internet-access to the information, supplement of DBs by means of the analysis of the information based on artificial intelligence methods, the use of different DBMS and operational systems, the use of servers of different types, and integration of DBs.
Three approaches to DB integration: Data Warehouse with ETL (Extract, Transform, Load)-technology, EII (Enterprise Information Integration)-technology and EAI (Enterprise Application Integration)-technology are discussed. The limitations of these approaches in the solution of problem of integration of DBs on properties of inorganic substances and materials are noted. The combined way that applies both EII and EAI technologies is proposed. This approach is based on an application of metabase. It is a special database that stores metadata on contents of integrated DBs, namely, about chemical systems and substances, which are identified, firstly, by set of chemical elements – components of systems, and by their content, and, secondly, by data on crystal structure of phases. Metabase contains also information about properties stored in different DBs, and other data. This information has enough to make search for relevant systems, data about properties and substances. The possibilities of expansion of integrated system of DBs on properties of inorganic substances and materials are discussed.
The integrated system of DBs is assessed for registered users: www.imet-db.ru.
Keywords: database on properties of inorganic substances and materials, DB integration, Internet, metabase, Enterprise Application Integration, Enterprise Information Integration.

Best Practice Materials Data Management For Aerospace And Energy

ABSTRACT
In aerospace, energy and defense engineering, quality is paramount. All design and production decisions must be carefully modeled using accurate materials property data. Often, this data must be certifed by internal experts or external regulators. So using the right reference sources is vital. Excellence in managing and analyzing test data is also important in order to guarantee the reliability of internal design data and the quality of your production materials. Such data consists of a huge range of parameters — materials, properties of interest, components, operating conditions, tests, analyses, and more — posing a formidable information management challenge. Best practice also demands that your design decisions are fully traceable and that problems can be quickly diagnosed. Ideally, all relevant data and analyses should be retained, along with the connections between them.
Organizations in these sectors also need to deploy approved materials information effectively across their networks — for example, making it easy to access and use for your stress engineers and analysts as they perform CAE simulations. In an environment where information can be highly sensitive, security is essential in this deployment process. Data must get to those authorized to use it, when and where they need it — and to no-one else.
Yet the best organizations want to do more than just cope with overwhelming materials data. They aim to turn it to their advantage. They may wish, for example, to continuously assess data on the performance of materials in use, in order to improve design allowable values. Or they may wish to use materials information to support key decisions as they optimize their materials strategies.
GRANTA MI is the leading system for materials information management. Its development is guided by the Material Data Management Consortium (MDMC), a collaboration of top organizations such as NASA, GE - Aviation, Rolls-Royce, Honeywell, and Oak Ridge National Labs.

Martin-Luther-King-Plz. 6, 20146 Hamburg, Germany
ABSTRACT
A knowlegde system is not a list of floating point numbers and text but a computer system with validated data and applied rules and data specific functionality. SciDex, is a tool for new types of knowledge systems and has generalized object definitions to serve chemistry, physics and biology. It has methods to store, normalize, validate, analyse, compare and predict data. It is currently used for example for LiqCryst (LCD, liquid crystals), Landolt-Börnstein, natural products (AntiBase), NMR (29Si-NMR, 17O-NMR) and multi-user online inventory systems (CLAKS), e.g. see:
http://liqcryst.chemie.uni-hamburg.de
http://lb.chemie.uni-hamburg.de/
The aim of SciDex is not to develope highly specific computer systems for single applications, but to cover all areas of materials study in just one system.
The data generalized data model and the analysis methods of SciDex will be described.

Development of a Network Database for Thermophysical Property Data
Tetsuya Baba
National Institute of Advanced Industrial Science and Technology
AIST Tsukuba Central 3, 1-1-1, Umezono, Tsukuba, Ibaraki 305-8563, JAPAN
ABSTRACT
A network database for thermophysical property data has been developed and opened to the Internet by collaboration of scientists, researchers, and engineers who produce data by measurement or evaluation in Japan. This database accumulates thermophysical property data such as thermal conductivity, specific heat capacity, thermal expansion coefficient, surface tension, viscosity and density etc. for variety of materials including solids, high temperature melts and fluids. At present, thermophysical property data of, 1) standard and basic data, 2) functional materials, 3) reference data of fluids and high temperature melts, 4) thin films and boundary thermal resistances, 5) materials for use at high temperatures, 6) materials for use at low temperatures, 7) organic materials and inorganic materials, are stored.
This database uses hierarchy structure for material classification to which thermophysical property data is assigned. Scope and overall coverage of the database can be viewed by an explorer like user interface. The target material can be searched following the hierarchy structure from higher class to lower class. A powerful and flexible search engine has been developed with two modes of search, "material search" and "property search". The material search can find target materials from information such as material name, chemical formula, material code, etc. The property search can find materials which have physical properties within the specified range. A user friendly graphical user interface has been developed to access thermophysical property data via internet efficiently.
This database can be accessed at the url “http://www.aist.go.jp/RIODB/TPDB/DBGVsupport/English/”. Keywords: thermophysical property, database, network, internet, graphical user interface

Application of Materials Databases to Composite Materials Design
Yibin Xu Materials Database Station, National Institute for Materials Science, Tokyo, Japan
CompoTherm, a thermophysical property prediction system for composite materials has been developed by National Institute for Materials Science (NIMS) and opened to the Internet access (http://composite.nims.go.jp/) since April 1st, 2005. This system offers users a platform to design a new composite material using the materials stored in multiple NIMS Materials Databases (http://mits.nims.go.jp/db_top_eng.htm), and predict the thermophysical properties such as density, specific heat, thermal conductivity and thermal diffusivity of the designed material, basing on the property data of the component materials and the composite structure. Tow simulation methods, analytical method and finite element method are provided to calculate the thermal conductivity of composite materials. And a knowledge base is available to help the users to understand the theoretical foundation of composite material design and property prediction. The system have been used to calculate the interfacial thermal conductance of SiC-particles-reinforced aluminum alloy matrix composites, the thermal conductivities of SiC-whisker-reinforced aluminum alloy matrix composites and thermal-sprayed Zr2O thermal barrier coatings. The calculated values are in good agreement with the experimental ones. Acknowledgement A part of this work was financially supported by The Budget for Nuclear Research of The Ministry of Education, Culture, Sports, Science, and Technology based on the screening and counseling by The Atomic Energy Commission.

Why composite material?
• Multi-requirements on material property
•
• Difficult to be satisfied by single phased material
• Improve material performance by mixing two or three phases
• Infinite combination of materials and structures
• Constitutional and structural design and optimization by computer simulation
