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

三种F3B复合材料的线收缩率随SiC含量的增加而减小

Abstract

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.
