摘要
考察了几种不同基体和状态的ＳｉＣ晶须增强铝合金复合材料在拉伸变形过程中流变应力的变化情况，发现复合材料的强化效果与基体强度有关，混合法则（ＲＯＭ）对复合材料抗拉强度的预测与实验值偏差较大，基体强度高的复合材料在拉伸变形过程中出现低应力屈服现象，复合材料的加工硬化能力明显高于基体。
The flow stresses of several aluminium alloys and SiC W reinforced composites during tensile deformation have been studied. It shows that the strengthening effect of the composites relates to the strength of the matrix alloys; the rule of mixture (ROM) is not applicable for the prediction of the tensile strength of these composites; the yield stresses of those composites with higher strength matrix alloys are lower than those of the matrix alloys, and the work hardening ability of the composites is much higher than that of the matrix alloys. Some possible reasons of these results are discussed in this paper.
