摘要
简要介绍了含RE、B的高导电率电工圆铝杆的试验研究。结果表明:电工圆铝杆中添加RE可改善力学性能,添加B可提高导电性能;当B在电工圆铝杆中的质量分数超过0.045%时,塑性有所下降;RE的质量分数超过0.3%时,对导电性有不良影响。
<Abstrcat>The technology research of high conductivity Al-RE-B electrical pole are brief introduced.The results indicated:the mechanical properties of electrical pole were better,when RE was added,and the electrical conductivities of electrical pole were improved,when B was added.When the content of B was over (0.045%),the plasticity of electrical pole was declined.When the content of RE was over (0.3%),the conductivity was reduced.
