研究了SiC颗粒增强铸造铝基复合材料F3B的线收缩特性。采用“直测法”和“ZQS-2000型双试棒合金热裂—线收缩仪”测试三种F3B复合材料(SiC体积分数分别为10%,15%,20%)及其对应的基体合金的线收缩。研究结果表明,三种F3B复合材料具有比对应基体合金良好的线收缩特性,三种F3B复合材料的线收缩率随SiC含量的增加而减小。
研究瞭SiC顆粒增彊鑄造鋁基複閤材料F3B的線收縮特性。採用“直測法”和“ZQS-2000型雙試棒閤金熱裂—線收縮儀”測試三種F3B複閤材料(SiC體積分數分彆為10%,15%,20%)及其對應的基體閤金的線收縮。研究結果錶明,三種F3B複閤材料具有比對應基體閤金良好的線收縮特性,三種F3B複閤材料的線收縮率隨SiC含量的增加而減小。

The linear contraction characteristics SiC particulate reinforced cast aluminum matrix composite F3B was studied. The linear contraction of three kinds of F3B composite (φ(SiC)=10%, 20%, 30% respectively) and their correspondent matrix alloy were measured by means of“direct measurement” and “ZQS-2000 twin-bar alloy hot crack-linear contraction apparatus”. The results showed that the three F3B composites have better linear contraction characteristics than the correspondent matrix alloys. The linear contraction rate of the three F3B composites decreases with the increase of SiC content.
