研究了雾化沉积ＳｉＣｐ／２０１４复合材料的时效行为。结果表明，在ＳｉＣｐ／２０１４的时效过程中，峰值时效的主要强化相为β相（Ｍｇ２Ｓｉ），其最佳的时效工艺为５０２℃固溶４０ｍｉｎ，１７０℃时效４．５ｈ。
The aging behavior of atomized SiCp / 2014 composites was studied. The results show that during the aging process of SiCp / 2014, the main strengthening phase of peak aging is β phase (Mg2Si). The optimum aging process is solution treatment at 502 ℃ for 40min and aging at 170 ℃ for 4.5h.
