采用搅拌摩擦加工技术制备了Al-Ni复合材料

并对复合材料进行不同温度的后热处理。结果表明

Al-Ni复合材料主要相为Al3Ni

且有部分Ni粉未完全反应;通过后热处理可促进金属间化合物形成

经过450℃×6h后热处理

生成相为Al3Ni和Al3Ni2;对合金化材料进行热处理时

晶格缺陷的增生、扩散以及缺陷的相互作用导致反应的进一步进行。

A series of Al-Ni composites were fabricated by friction stirring processing

and then were post-treated at different temperatures.Results show that the Al-Ni composites prepared are composed of Al3 Ni

and a few Ni is not participated into reaction.After heat treatment at 450℃for 6h

the reaction degree between Ni and Al will be increased

and Al3Ni、Al3Ni2phases are generated.Hyperplasia

diffusion of defect and interaction of defect can deduce reaction to be further conducted during heat treatment process.
