【摘要】：采用攪拌摩擦加工技術(shù)制備了Al-Ni復(fù)合材料,并對(duì)復(fù)合材料進(jìn)行不同溫度的后熱處理。結(jié)果表明,Al-Ni復(fù)合材料主要相為Al3Ni,且有部分Ni粉未完全反應(yīng);通過后熱處理可促進(jìn)金屬間化合物形成,經(jīng)過450℃×6h后熱處理,生成相為Al3Ni和Al3Ni2;對(duì)合金化材料進(jìn)行熱處理時(shí),晶格缺陷的增生、擴(kuò)散以及缺陷的相互作用導(dǎo)致反應(yīng)的進(jìn)一步進(jìn)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，
