摘要

本文研究了Fe元素对稀土过共晶Al-Si系活塞合金室温和高温机械性能的影响。随着铁含量的增加

合金的室温强度、硬度下降;在Fe含量小于0.7％时

高温强度增加

超过0.7％后开始下降。铁含量小于1.0％时

合金的高温塑性变化不大。

Abstract

The effect of mechanical properties on Fe in rare earth hypereutectic Al-Si piston alloys has been investigated under room and elevated temperature. It is demonstrated that the room temperature strength

hardness decreases with the increasing of Fe content

the high temperature strength increases before the Fe content reach 0. 7% and decreases over. Its high temperature elongation change little while the Fe content is less than 1.0%.
