摘要
针对压力在瞬时液相扩散(TLP)连接不同阶段的不同作用,提出了多压力工艺模型。采用多压力工艺模型,在1230-1260℃,氩气保护,对T91钢管进行了瞬时液相扩散连接(TLP),研究了多压力工艺模型下接头的力学性能和显微组织。结果表明:在多压力工艺模型下,T91钢管TLP接头的力学性能和显微组织远优于一般工艺。分析得出多压力工艺模型既能充分发挥压力在TLP连接中的作用,又能避免高压带来的不利影响。
In view of different functions of pressure in different periods, multi - pressure craft model is multi -pressure craft model, pressure TLP is proceeded on T91 steel pipe at 1230 - 1260℃and argon shield, microstructure and mechanical property of joint is researched. The result shows that microstructure and mechanical property of TLP joint with multi - pressure craft model is better than ordinary pressure display function fully in TLP bonding and avoids the adverse effect one. On multi -pressure craft model, with high - pressure.
