Materials for high temperature applications – hardening and damaging mechanisms

Anotace

The data and the knowledge necessary for the design of materials designated for service under high loads at high temperatures will be collected and applied using international cooperation. In two types of presently developed materials, one used for effective coal combustion, the other for energy production using fusion reaction the response to high temperature mechanical and thermal loadings will be studied. The mechanisms of hardening will be studied by investigating the interaction of dislocations with different types of obstacles (other dislocations, precipitates, carbides, dispersed foreign particles). The damaging processes during creep, cyclic creep, low cycle fatigue, thermomechanical fatigue and fatigue-creep interactions will be studied in order to reveal damaging mechanisms in high temperature service.
