Abstract

Ni₃Al intermetallic was prepared from 3Ni + Al mixtures by combustion synthesis in a mode of thermal explosion under pressure. The process was characterized by the barograms of thermal explosion taken upon variation in precompaction pressure and delay time for compaction pressure. Process conditions for preparation of Ni₃Al were optimized. Our approach can be readily applied to cost-effective fabrication of other superalloys using similar reactive SHS mixtures.

加压热爆炸制备Ni 3 Al：预压压力和压实延迟时间的影响

摘要

Ni ₃ Al金属间化合物由3Ni + Al混合物通过燃烧合成在压力下热爆炸的方式制备。该过程的特征在于预压缩压力和压实压力延迟时间变化时所产生的热爆炸柱状图。优化了制备Ni ₃ Al的工艺条件。我们的方法可以很容易地应用到使用相似的反应性SHS混合物的具有成本效益的其他超级合金制造中。
