【摘要】：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。
[Abstract]:The Al-Ni composites were prepared by friction stir processing, and post-heat treatment of the composites at different temperatures was carried out. The results showed that the main phase of Al-Ni composites was Al3Ni, and some of Ni powder did not react completely, and the formation of intermetallic compounds could be promoted by post heat treatment, and the phases were Al3Ni and Al3Ni2; after heat treatment at 450 鈩，
