摘　　要：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 2 0 0 0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 % ,2 0 % )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 。The linear contraction characteristics SiC particulate reinforced cast aluminum matrix composite F 3B 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 F 3B 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.
