At thick-walled tubes made of INCOLOY 800 which are exposed to tensile stress (primary stresses), unstationary temperature fields are produced by cyclical, inductive heating of the surface, which lead to secondary stresses. The strains caused by it are measured and compared with strains under homogeneous temperature conditions. In order to operate clearly within the creep range, the experiments are made at temperature levels of over 800 C. Mathematical analyses of the experiments are performed with finite-element programs using simple material laws. By means of systematic investigations, influence parameters are identified and evaluated. (orig.)An dickwandigen Rohren aus INCOLOY 800, die einer Zugbeanspruchung (Primaerspannungen) ausgesetzt...
