研究了硼对工业纯Al导电性的影响研究结果表明使用Al－3．35％B中间合金，处理含过渡元素（Ti，V，Cr，Mn）为0．01－0．023％（质量分数，下同）的工业纳Al，电阻率都有一定程度的降低，过渡元素含量愈多，效果愈明显加入硼后，反应生成块状Ti，V；Fe的硼化物和团絮状Ti，V，Fe，Zr的硼化物加硼后使Ti，V，Zr脱离固溶状态，形成硼化物析出，是增加Al导电性的主要原因，对生成的硼化物进行分析，未发现化合物中有Cr，Mn元素存在 The effect of boron on the electrical conductivity of industrial pure Al was studied. The results show that the use of Al-3.35% B master alloy for the treatment of transitional elements (Ti, V, Cr and Mn) of 0.01-0.023% , The same below) industrial Al, the resistivity has a certain degree of reduction, the more the transitional element content, the effect is more obvious after the addition of boron, the reaction of massive Ti, V; Fe boride and flocculent Ti, V , Fe, Zr boride added to the Ti, V, Zr from the solute state, the formation of boride precipitation, is to increase the conductivity of Al is the main reason for the formation of boride analysis found no Cr, Mn element exists
