Effect of intergranular stress on creep deformation in 316H during high temperature asymmetric cyclic loading - Part 2

Abstract: Creep lifetime of high temperature power plant materials are significantly affected due to predicted and unpredicted cyclic loading during plant operation. Our previous study has shown, during high temperature cyclic loading, internal stresses are generated in 316H austenitic steel due to inhomogeneities in deformation which opposes the applied stress, termed as back stress. Generation of back stress and its effect on creep deformation in 316H austenitic steel can be estimated by studying grain family specific intergranular strain using neutron. In the proposed experiment, the effect of cyclic load generated back stress on creep deformation will be studied by simulating real life plant operation conditions. The results will contribute both to extending analytical model of back stress into creep studies and also to improving lifetime assessment code of the power plants for EDF energy
