摘要
研究了混合稀土对高铝锌基复合金高温力学性能的影响． 结果表明：在ＺＡ２７ 合金中，添加适量的稀土后，晶界处形在了相当数量硬而分散的复杂成分化合物，从而使合金在１５０ ℃时的强度、硬度有明显提高，塑性和冲击韧性也有的改善．
The influence of mixed RE on the high temperature mechanical properties of high Al Zn base alloys has been inrestigated. The results show that, with addition of RE in appropriate contents, quite a number of hard dispersed complex compounds are formed at the grain boundaries. It results in the apparrent increase in strength and hardness, also in some inprovement on plasticity and impulsive tenacity of the alloys at 150 ℃.
