摘要
研究了相变扩散焊接中热循环对焊接强度的影响。通过对热循环温度、冷却速度、热循环次数对合金元素扩散行为和焊口组织影响的分析,确定了热循环参数的选择原则。
Effect of thermal cycling on bonding strength of steels in phase-transformation diffusion bonding was studied. The principle of the determination of thermal cycling parameters was discussed by analyzing the effects of cycling temperature, cooling rate and the number of thermal cyclings performed on the diffusion behaviour of alloying elements and joint structures.
