Microstructures of AZ80 + xSr Alloy and Existing forms of Sr

AZ80+xSr合金的组织和Sr的存在状态

The interface and fracture surface of SiC P / AZ80 composites were examined by SEM and TEM .

本文用SEM，TEM研究了SiC颗粒增强AZ80镁合金复合材料的界面结构和断口形貌。

Examination of the fracture surface indicated that the bonding strength between SiC and matrix alloy was stronger than that of matrix . The SiC particles segregation is the main cause of the SiC P / AZ80 composite failure .

对复合材料断口观察表明，SiC颗粒与镁合金界面之间的粘结强度大于基体的撕裂强度，SiC颗粒的聚集、团聚是导致复合材料断裂的主要原因，且复合材料的断裂形式趋向脆性断裂。
