| 摘 要： | 采用拉伸力学性能测试、金相显微镜、扫描电镜(SEM)、能谱分析(EDS)等手段,研究了混合稀土(Y:Ce=1:1)对铸态Al-B电工圆杆显微组织和性能的影响,并探讨了轧制变形量对稀土铝电工圆杆综合性能的影响。结果表明：当混合稀土的添加量为0.25%时,铸态铝电工圆杆的综合性能较佳,导电率为63.74%IACS,抗拉强度达83MPa,与未添加稀土试样相比较,导电率提高了1.44%IACS,抗拉强度提高了11MPa。轧制处理使稀土铝电工圆杆的导电率呈小幅度下降,但抗拉强度增加,当轧制变形量为72%时,试样综合性能较佳,导电率为61.30%IACS,抗拉强度达123MPa。

| Abstract: | The effect of combined addition of Y and Ce on the microstructure and properties of Al-B electrician round rod was investigated by means of tensile test, optical microscopy, SEM and EDS. The change of microstructure and properties of rare earth Al electrician round rod under different rolling deformation was discussed. The results indicated that as-cast Al electrician round rod has favorable comprehensive properties with 0.25% combined addition(Y:Ce=1:1), of which the electrical conductivity and tensile strength reach 63.74%IACS and 83MPa, respectively. Compared with the sample without rare earth, its conductivity and tensile strength had increased 1.44% IACS and 11MPa, respectively. Under rolling processing, the conductivity of aluminum electrical round rod has a slight decrease, but tensile strength of specimen increase. The rolling state sample with 72% deformation has a better comprehensive performance, of which the electrical conductivity and tensile strength reach 61.3%IACS and 123, respectively. |
