| 摘 要： | 对高铝锌基ＺＡ２７合金在室温下的拉伸断裂特征进行了研究，结果表明，ＺＡ２７合金在拉应力作用下，其裂纹源始于树枝晶间的α＋η共晶组织，裂纹扩展过程是以沿α＋η，剪断树枝状α相和ε相的方式进行的，并探讨了ＺＡ２７中各相对其强度和塑性的影响。

| Abstract: | The fracture characteristic of high aluminum Zinc-based alloy (ZA27) under the tensiletest at the room temperature was studied. The results show that the cracks of ZA27 alloy form ata+ry eutectic phase, develop by propagating along the phase and cuting through the dendrite aphase and E phase. The influence of every phase in ZA27 on the strength and ductility wasanalyzed. |
