“…Post-weld heat treatments are usually used for: stress relief of residual stress due to the weld thermal cycle [249] or optimization of the tensile properties of the welded material by obtaining a more suitable microstructure [250,251]. Accordingly, by choosing appropriate heat treatment parameters (temperature and time) the mechanical properties of the welds can be improved.…”

“…The reduction in high tensile residual stresses caused by PWHT is particularly important since high tensile stresses are usually responsible for early microcracks and damage. In a previous publication [27], FE modelling of a welded steel component experiencing PWHT has allowed for the redistribution of stresses during thermal cycles due to the associated changes in the material yield stress, but it has not included the effects of creep. In another publication [23], the redistribution of stresses due to creep during PWHT holding time, obeying the Norton law, has been accounted for in the FE simulation in addition to including plasticity effects, brought about thermally, owing to a temperature-dependent yield stress.…”
