摘要
在对结构钢 (40Cr)同材、结构钢 (40Cr)与工具钢 (T1 0A、GCr1 5 )异材实施恒温超塑性固相焊接可行性全面分析的基础上 ,通过对结构钢、工具钢待焊面表层实施高频淬火组织超细化处理 ,在非真空、无保护气氛下 ,系统地探讨了恒温超塑性固相焊接工艺参数对接头质量的影响 .试验结果表明 :只要选择适宜的焊接工艺参数 ,经短时间压接可使接头强度达到或接近 40Cr母材的强度 ,实现钢的同材和异材恒温超塑性固相焊接 .
Based on analysis of the probability for isothermal superplastic solid phase welding of same base metals of structural steel (40Cr),different base metals of structural steel (40Cr) to tool steels(T10A,Cr15).the structure ultrafining treatment of the welded surface of structural steel and tool steels can be made through high frequency induction surface quenching. Effect of the processing parameter for isothermal superplastic solid phase welding to the quality of welding joint have been examined under non vacuum and non shield gas. The experimental results indicates:if having a suitable welding processing parameter of isothermal superplastic solid phase welding, it can be finish between same base metals and different base metals in short time ,which the tensile strength of welding joint can be as high as or close to that of 40Cr base metal.
