含钛铸造Al-Si合金活塞粗晶断口分析
摘要
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)
2
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)
2
相发生穿晶解理断裂而形成的解理面。Ti(AlSi)
2
粗晶系合金熔化工艺不当造成
并提出了控制措施。
Abstract
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
