摘要：
The influence of post weld heat treatment on hardness and impact toughness properties of weldments of 1Cr0.5Mo and 2.25Cr1Mo steels has been investigated. Post weld heat treatment significantly reduced the hardness and the impact transition temperature and increased the upper shelf energy. The decrease in hardness was essentially larger for 2.25Cr1Mo than for the other steel, probably due to the presence of martensite in the as-welded condition in the former material. The decrease in the impact transition temperature was largest for 1Cr0.5Mo.
