Abstract

The effects of Ce and Sn addition on microstructure of AZ91 magnesium alloy have been described.It is found that the grain size in the microstructure can be obviously refined with Ce addition,and rod-like Al-Ce compound can be observed.The Al-Ce phase in the matrix gradually grows and is aggregated with the Ce addition more than 0.6%,resulting in the fading of reining effects.Long rod-like Al-Cu phase can be further refined and diespersively distributed into the AZ91-0.6Ce alloy with Sn addition.The refining effects of Ce and Sn mixed addition are superior to those of Ce addition only in T4 treated Alloy,in which the grain size is decreased from 150²00μm to 60⁸0μm with 0.6% Ce and 0.3%⁰.5%Sn mixed addition.

摘要

研究了Ce、Sn对AZ91合金微观组织的影响。试验发现

加入Ce后基体晶粒得到明显细化

同时基体中出现棒状的Al-Ce化合物。当合金中Ce加入量超过0.6%时

基体中Al-Ce相逐渐偏聚长大

晶粒细化效果下降。向AZ91-0.6Ce合金中添加不同含量的Sn时发现

合金中长棒状的Al-Ce相变细小且弥散分布于基体中。T4热处理后发现

Ce、Sn复合添加的合金比单独添加Ce元素的合金晶粒更加细小。添加0.6%的Ce+0.3%～0.5%的Sn后AZ91合金的晶粒由150～200μm细化到60～80μm。
