以光学金相、电镜扫描和电子探针分析方法为主要手段

对含钛（Ti）铸造Al-Si合金活塞粗晶断口进行了观察分析

指出粗晶Ti（AlSi）

相是造成活塞脆性断裂的原因

断口鱼鳞闪亮点实际是粗晶Ti（AlSi）

相发生穿晶解理断裂而形成的解理面。Ti（AlSi）

粗晶系合金熔化工艺不当造成

并提出了控制措施。

By means of optical metalloscope

scanning electron microscope and electronic probe

authors have examined and analysed the of breakage coarse grains section of Ti-bearing Al-Si piston alloys

The cause of piston fracture

and the wag of control have been suggested.
