SiC_P／Al复合材料界面约束探讨

Interface Constraint of SiC/Al Composites

分析了金属基复合材料韧性下降的原因，并通过简单的串联力学模型讨论金属基体对颗粒约束的影响。在ＳＥＭ下的拉伸试验，直接从微观上证明了这种约束的作用。

For the reasons of toughness decreasing of SiC/Al composites, the constraint effects of particles on the metal matrix are discussed with the simple series model of two-phase materials. Through the tensile test in SEM, the constraint effects of particles have been investigated qualitatively in microscope.
