摘要：

High temperature component design is very important in different industrial fields. This paper discusses work done in Germany on the design of metallic components for the Helium Cooled High Temperature Reactor. Candidate materials for application at the different temperature regions are presented. Criteria are developed to specify the allowable strength values of the materials (S(m), S(t)) for use in design codes. The following typical relevant phenomena are treated and discussed: -creep under uniaxial and multiaxial conditions up to temperatures of 1000-degrees-C; -creep fatigue interaction, where holding times during the stress strain cycles have a great influence on the life time; -creep buckling for pressure loaded shells with initial imperfections; -creep ratcheting as a phenomenon, where cyclic secondary stresses produce enhanced deformations; -fracture mechanics at high temperatures with the aspects of creep crack growth and fatigue crack growth.
