Dissimilar metal weld failures between low alloy Cr-Mo ferritic steels and austenitic stainless steels made with Ni-base filler metals are typically observed along the fusion line. Such DMW failures often exhibit the onset of damage well before their

The quantification of key microstructural parameters as a function of aging or creep exposure time is commonplace in the assessment of 9Cr Creep Strength Enhanced Ferritic (CSEF) power-plant steels. In these studies, the sample is either assumed chem

This article will highlight the investigation of the dissimilar metal weld (DMW) between a Grade 22 pipe (2.25 wt% Cr) welded to a Grade 91 header piece (9 wt% Cr) which was in use for 79,000 h at a service temperature of 570 °C at a UK fossil fuele

The microstructure in the heat-affected zone (HAZ) of multipass welds typical of those used in power plants and made from 9 wt pct chromium martensitic Grade 92 steel is complex. Therefore, there is a need for systematic microstructural investigation
