For this purpose systematic evaluations of data are performed for mechanical, physical and technological properties. With the generated values material databases are established. At present systems for shape memory alloys and stainless steels are developed. Materials design Mechanical property data for stainless steels and aluminium alloys are analysed to establish models which can used in materials design and adapt composition and microstructure of materials to applications. Creep failure is a major problem in many types of high temperature plants.
Failures frequently occur in welded joints.
To improve this situation new design principles are established by modelling the creep behaviour of joints with finite element stress analysis. The results of the analysis are also used when determining the residual life time of fossil fired power plants. Design principles against brittle failure for pressure vessel applications are developed. Most recently cast irons and steels have been studied. Integration to design Selection of materials in industrial practice is often made with empirical non-systematic procedures.
