摘　　要：通过电导率测试、拉伸试验、SEM、EDS、金相显微镜观察等手段,研究稀土元素铈、镧的添加量对A1-B电工圆杆组织和性能的影响.结果表明,当稀土元素铈、镧的添加含量分别为0.05％～o.30％、0.10％～0.35％时,Al-B电工圆杆具有良好的综合性能.The effects of rare earth elements of Ce and La on microstructures and properties of Al-B electrician round rod were studied by means of conductivity measurement, tensile test, SEM, EDS and metalloscope observation. The results show that Al-B electrician round rod has favorable conductivity and mechanical properties with the addition of Ce and La of 0.05%-0.30% and 0.10%-0. 35% respectively.
