Abstract
In the collaborative programme between MPA, Stuttgart, and the Institute for Materials Science and Welding Technology at the Technical University, Graz, within the framework of COST 505 “Materials for Steam Turbines”, the creep‐rupture behaviour of the dissimilar weldment 1%CrMoV/12%CrMoV was investigated. Independent of the effects given by the welding process, weld metal and post weld heat treatment, the fine‐grained zone in the HAZ of the lower alloyed steel grade was life‐determining after long‐time creep loading. The decarburized coarse grained HAZ near the fusion line is critical at higher stress levels, e.g. breakdowns.
