摘要

采用微观组织结构观察、硬度测试以及电子探针分析的方法

对T91与12Cr1MoVG异种钢焊缝接头进行研究。结果表明:焊缝和热影响区硬度HV达到425以上

在T91侧热影响区出现过饱和马氏体组织

电子探针分析表明在T91侧热影响区存在碳富集区

并形成增碳层。

Abstract

The weld joints of T91 and 12 Cr1 MoVG dissimilar steels were studied by means of microstructure observation

hardness test and EPMA analysis. The results show that the hardness of weld seam and HAZ is above 425

and the supersaturated martensite structure appears in HAZ on T91 side. EPMA indicated that carbon-enriched region existed in the heat affected zone side T91 and carbon layers formed.
