INFLUENCE OF HEAT TREATMENT AFTER WELDING UPON WELD-JOINT STIFFNESS OF HCM2S STEEL
摘要
采用焊接热模拟技术
确定了从焊接粗晶区韧性的角度考虑
取消HCM2S钢焊接对于预热是可行的
其合适的焊后热处理范围为(710~750)℃×2h。HCM2S钢焊接粗晶区在550℃左右时
存在再热脆化倾向
再热脆化的敏感温度范围需进一步研究确定。
Abstract
By using weld thermal simulation technology
and considering from view point of stiffness for the weld coarse crystal region
it is determined the elimination of preheating for HCM2S steel welding is fully feasible
the suitable heat treatment specification to be(710-750)℃×2 h.At temperature about 550 ℃
the weld coarse ccrystal region of HCM2S steel exist tendency of reheat embrittlement
however
the sensitive temperature range of reheat embrittlement is waiting to be further studied and determined.
