铝—硅共晶活塞合金的Na、P变质

Na or P Modification of Eutectic Al-Si Piston Alloys

本论文致力于KS1275活塞合金分别经Na、P变质后,在机械、物理性能以及铸造性能等方面的比较,同时,基于铸造理论和实践结果,对影响P变质效果的一些重要因素进行分析、小结.

This article is dedicated to the comparison of the mechanicaKphysical properties and casting behavior of KS1275 piston alloy modified by Na or P. Meanwhile, in view of casting theory and practice achievements,a brief summary of factors which influence the effect of P modification is achieved.
