A Study of Microstructure in an Alloy 182/ Low Alloy Steel Dissimilar Weld Joint
概要
The chemical composition, hardness, characterization of microstructure in fusion boundary region of di ssimilar welds between SQV2AQ low alloy steel and INCONEL Alloy 182 were evaluated. It was found that microstructure and composition transition region existed across the fusion boundary region. Composite carbide and Cr-carbide was observed, and martensite laths existed in both sides of the fusion boundary.
