The Weldability Of Cr-Mo Steels For Fossil Energy Applications, Mark W. Richey
The Weldability Of Cr-Mo Steels For Fossil Energy Applications, Mark W. Richey
Masters Theses
This research program was undertaken to provide fundamental and basic metallurgical information on the behavior of the heat-affect zone (HAZ) in Cr-Mo steel welds, as well as practical information on their relative weldability. The principal work was the evaluation of the stress-relief cracking (SRC) and hydrogen-assisted cracking (HAC) susceptibility of Cr-Mo steels ranging in Cr content from 2 1/4%-12%. Differences in observed cracking behavior were contrasted with differences in composition, on-cooling transformation behavior and weld microstructure.
The test methods were varied to investigate the effect of preheat, post-weld heat treatment (PWHT) , metallurgical structure and restraint (externally applied) on the …
