研究了温度对 Ａｌ Ｔｉ Ｂ 中间合金细化效果的影响。试验结果表明， Ａｌ Ｔｉ Ｂ 中间合金的细化效果不仅取决于其本身的结构形态， 而且与细化工业纯铝的温度密切相关。比较了国内外三种 Ａｌ Ｔｉ Ｂ中间合金的细化效果随温度的变化规律， 发现， 其变化规律和达到最佳细化效果不同。
The effect of temperature on the refining effect of Al Ti B master alloy was studied. The experimental results show that the refining effect of Al Ti B master alloy depends not only on its own structure, but also on the temperature of refined pure aluminum. The variation law of the refining effect of three kinds of Al Ti B master alloys at home and abroad with the temperature is compared. It is found that the variation regularity and the best refinement effect are different.
