摘　　要：采用对比实验方法，通过电导率测试、拉伸试验、宏观组织观察、金相显微镜观察等实验，研究稀土元素Ce、La的不同添加量对Al-B电工圆杆组织和性能的影响。结果表明，当稀土元素Ce、La的添加含量（质量分数）分别为0.05％-0.30％、0.10％-0.35％时，Al-B电工圆杆具有良好的综合性能。The influence of different additive amounts of rare earth elements of Ce and La on microstructure properties of Al-B electrical round rod were studied by contrast experiment method, which included electrical conductivity test, tensile test, macroscopic observation, metallographic microscope observation and so on. The results showed that the Al-B electrical round rod was good conductivity and mechanical properties when the content of Ce and Lawere 0.05%-0.30% and 0.01%-0.35%.
