摘要
用扫描电镜观察了 SiC 晶须增强 Al 基复合材料疲劳裂纹的形成扩展特征,研究了 SiC 晶须分布、晶须与基体界面及基体中的缺陷对疲劳裂纹形成的影响。
The characteristics of fatigue cracks initiation and propagationin a SiC(W) reinforced Al alloy have been observed by SEM.The effect ofthe SiC(W) distribution,the interface between SiC(W) and matrix and defectsin the matrix on fatigue crack initiation has been investigatsd.
