【摘要】 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。更多还原

【Abstract】 The refining effect of the temperature on the AlTiB master alloys has been investigated.The rsults of experiments showed that the refining effect of AlTiB master alloys depends on both their structure and morphology,and the temperature of refined commercial pure aluminum melt.Variation rule of refining effect with temperature for 3 kinds of AlTiB master alloys was compared.It has been found that different kind of AlTiB master alloy has varying temperature reaching optimal refining effect.更多还原
