摘　　要：探讨了结构钢与工具钢待焊接区表面高频淬火后超塑焊接的可行性及影响因素,并对接头组织进行了观察和分析。试验表明,焊接区局部高频淬火后的结构钢与工具钢,在t0=10min、σ0=56.6MPa、 ε0=1.5×10-2min-1、θ=800℃、t=3.5min的压接条件下可实现良好的固态焊接,其接头强度达到40Cr母材强度。The probability and main effect factors of superplastic welding of structural steels and tool steels after high frequency induction hardening have been examined. The micro structures of welding joints were observed.The experiments shown that after high frequency induction hardening and the conditions as t_0 =10min, σ_0 =56.6MPa, _0=1.5×10^(-2)min^(-1), θ =800℃, t =5min,the two steels can be well welded by solid-state welding,and the strength of welding joints can achive that of 40Cr steel.
