摘　　要：在研制稀土AlMg3W合金的基础上．采用金相观察、X射线衍射等手段，并通过力学性能、耐磨性能、焊接性能、热膨胀性能等对比测试，系统地分析了稀土对AlMg3W合金显微结构及物理性能的影响。结果表明，当稀土含量为0．05％时，稀土AlMg3W合金的性能最佳。For systematic analysis of the influence of RE on microstructure and physicalproperties of AlMg3W alloy, the metallographic inspections and X-ray diffractions have beenundertaken, and contrast tests have been made with respect to the mechanics property,wearability, welding property, thermal expansion property. The results show that AlMg3W alloywith 0. 05 % RE has the optimum property.
