Description
Summary:High temp. component design requires the consideration of constructive aspects prior to design and dimensioning work. In the high temp. range of > 800 deg C special importance is attached to the failure modes "creep fatigue", "ratcheting" and "creep buckling" of Inconel 617, X6CrNi18 11, X20CrMoV12 1, and 20MnMoNi5 5. Comprehensive examinations of existing design rules considering these failure modes with regard to possible applicability for HTR-conditions have been completed. Corresponding calculations have pointed out that there is a promising potential for safe component design even for extreme temp. load conditions. These results have additionally confirmed that available elastic methods often cannot be used and would lead to very conservative approximations. Thus the improvement of simplified verification methods and the improvement of relevant constitutive equations is required in view of further development work in the field of high temp. component design. 5 ref.--AA
