采用镀Ni后焊接以改变焊缝金属的Ni含量,再经时效处理的“复合法”工艺对焊缝金属的相变温度进行控制.研究了镀层厚度和时效时间对焊缝金属相变温度的影响规律,利用DSC,EDS,SEM,OM和XRD分析了焊缝金属的相变温度、化学成分和组织形貌,并从析出相、晶粒择优取向及晶格畸变对马氏体弹性能和相变阻力的影响几方面分析了“复合法1”控制相变温度的机理.结果表明,增加焊缝金属Ni含量仅能增加马氏体的弹性能,导致相变温度降低；而时效处理在增加相变阻力的同时也降低了马氏体的弹性能,导致相变温度提高；控制“复合法”工艺参数则可以将焊缝金属中马氏体的弹性能和相变阻力控制在合理的范围内,使焊缝金属的相变温度As和Af与母材相当.
