【摘要】 Al-Si合金被广泛用于制造各种活塞,其中又以ZL109使用最为普遍。运用力学性能、金相分析、热分析、硬度实验等手段,对常德一派公司用挤压铸造生产的活塞进行评估,认为该产品的性能明显优于重力浇铸活塞,可满足涡轮增压的需求。更多还原

【Abstract】 Aluminum-silica alloys are widely used to produce all kinds of pistons.Among them,Chinese Industrial Standard ZL109 (Al-12%Si-1%Cu-1%Mg-1%Ni)aluminum alloy is used popularly.Some experiments like ultimate strength,hardness tests,metallographic and thermal analysis were carried out in this paper.By evaluation of pistons produced in squeeze casting in Changde Epoch Aluminum Ltd.,the results show that performances of these pistons possess better properties than those produced in gravity die casting and meet the requirements of turbocharged diesel engine.更多还原
