摘　　要：研究了焊后热处理对CF -62钢焊接热影响区粗晶区韧性的影响。指出CF -62钢焊接热影响区粗晶区在焊后热处理过程中有产生消除应力脆化的倾向 。The influences of post-weld heat treatment on the toughness of the coarse grain region of CF-62 steel HAZ are studied. The result shows that the coarse grain region of CF-62 steel HAZ possesses the tendency of stress-relief embrittlement during post-weld heat treatment. The mechanism of stress-relief embrittlement of HSLA (high strength low alloy) steel is discussed.
