【Abstract】 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.更多还原
