摘要

<正> 一、前言自从三十年代发现过共晶Al-Si合金加磷变质以来

各国对此开展了相当多的研究。但对于同时变质初晶Si及共晶Si组织的研究有待于进一步的深入。为了提高和改善合金的性能

更大限度地发挥共晶Al Si合金的性能潜力

本文采用磷、混合轻稀土对Al-Si18％合金进行联合处理。据资料报导

稀土在共晶Al Si合金中

可以变质共晶组织、提高合金的高温强度

这就为选取稀士进行双重变质

Abstract

In the paper

it was firstly described to use phosphorus and mixed light rare earth as a co-inoculator of Al 18%Si hypereatectic alloy. In the experiments

P-RE co inoculating technology was studied. Meanwhile

the research On hypereutectic alloy structure and other properties affected by added P RE. The co inoculator was carried out. It was testified by experiment result that Al-Si hypereutectic co-inoculated by P-RE could have good comprehensive properties and P-RE co-inoculation is an ideal twofold technology.
