【摘要】 在爆炸焊接的过程中,结合区一薄层基体金属,在高温下将发生熔化、熔解或化合。大量的检验结果表明,这种熔体内的化学和物理组成,与对应组元的一般相图内的物理和化学组成相似。这种相似性便为相图在爆炸焊接中的如下应用打下了基础:可以根据相图来估计对应的复合材料中的熔体的组成,估计金属材料之间的爆炸焊接性,估计它们的结合强度,估计后续热加工或热处理对结合性能的影响,从而为爆炸焊接工艺参数和热加工及热处理工艺参数的制订提供理论依据。更多还原

【Abstract】 A thin layer of fusion zone is fused and compounded at the high tem" perature in explosion welding process. Lots of expermental results show that the phases in the fusion layer are corresponding to those in the phase diagram of the system. Thus. phase diagrams could be used to predict the phase in the fusion zone, the explosion welding ability of metals the bonding stregth and the effect of later forming process and heat treatment to the bonding properties. In other words, phase diagrams are the theortica! basis of parameter selections of the explosion welding forming and heat treatment.更多还原
