Atlas of World Steels

The Atlas of World Steels is a database that allows cross-referencing international standards for various metals. It includes chemical composition and mechanical properties. There is an online demonstration-version of the software. Eagle International Software.

Staatliche Materialprüfungsanstalt (MPA), Universität Stuttgart Power plant materials database

The DIWA database is a system designed to provide concise material data for nuclear and conventional power plant materials, i.e. ferritic and austenitic steels used in pressure vessels and pipes. The most important categories include; static and impact strength, yield curve, Charpy, fracture mechanics, creep and relaxation. Also included are component testing results. The purpose of DIWA is twofold. It 1. combines material data that was determined in a very wide variety of different experiments and it will be used by MPA to store most of their experimental results. 2. is intended as a tool for power plant engineers to facilitate quick reference and in-depth information about structural materials. DIWA is based on the Oracle database system and runs on a PC under Windows 3.11. MPA has theoretical and experimental activities in damage studies, materials application and joining technology, strength calculations including those for systems and plants. The Testing Institute is further working with destructive and nondestructive testing of materials, constructive solutions and adaption of design principles to new materials. 

HIGHTEMP

The Swedish Institute for Metals Research, Stockholm. Creep and tensile properties of aluminium alloys and steels at elevated temperatures are covered. Creep and high temperature yield strength values for Al-alloys have been assessed, and they were used in the development of a new standard for high temperature properties of Al-alloys. This was a collaborative project with the European aluminium industry, where data was collected from the participating industries and from the open literature. Creep data was extrapolated to 30 000 h using time-temperature parameters like Larson-Miller. To take into account the time dependence of the high temperature yield strength values of Al-alloys, an established evaluation method was generalised. The new method was then used to derive values at elevated temperature in relation to those at room temperature. The experimental data points have been put into HIGHTEMP. This database was developed mainly for internal use. 

hot cracking data

The Federal Institute of Materials Research and Testing, Welding Information Services, in Berlin has a factual database and are working on an expert system on the hot cracking susceptibility of austenitic stainless steels and nickel base alloys after welding. The factual database is oracle based and includes hot cracking data on 70 parent materials, 50 filler materials, 350 parent material hot cracking tests, 200 filler material hot cracking tests, and 3300 hot cracking tests. New materials hot cracking test results are continuously entered. The expert system is in the development phase. 

SSDATA

In a collaborative effort between Scandinavian stainless steel producers and Materials Technology, The Royal Institute of Technology, Stockholm, mechanical, physical and technological property data for stainless steels has been collected and evaluated. A materials selection system has been provided. It is expected that the material users should get access to updated information on stainless steels through this databank. Corrosion data have also been assessed; for uniform corrosion, pitting, and chloride stress corrosion. As a part of this project assessment of uniform corrosion data was performed for 17 groups of stainless steels in about 500 corrosive media. The relative resistance to pitting corrosion for newly developed super-austenitic and duplex stainless steels has been identified.

NRIM. Data-Free-Way. Nuclear materials database system

A distributed database system named "Data-Free-Way" for the design and selection of advanced nuclear materials has been developed jointly by NRIM, Japan Atomic Energy Research Institute (JAERI) and Power Reactor and Nuclear Fuel Development Corporation (PNC). Main objective of the development is to share new and stimulating information for the development of these materials. To develop a more user friendly system in the near future and to supply the information on nuclear materials to Internet, several sites in Data-Free-Way are being introduced on WWW. The National Research Institute for Metals. NRIM has been devoted to the development and improvement of new and advanced metallic materials. In order to ensure the performance of existing materials the Institute has been working on the establishment of the reliability of materials, including research studies on the prediction of the life span of materials.
