Abstract
Magnetic Barkhausen noise (MBN) measurements have been carried out on 2.25Cr-1Mo steel tube to tube sheet weldments at weld, heat affected z one, and base metal regions on both sides of the weldment before and a fter post-weld heat treatment (PWHT). In the as welded condition, MBN peak height varies significantly, at different regions and an inverse linear relationship was observed between MBN peak height and hardness values. After the PWHT, the variation in the MBN peak height at differ ent locations is reduced significantly as is the variation in hardness . (C) 1997 The Institute of Materials.
