摘要
根据液体蒸气压与温度遵从克劳修斯克莱贝龙方程的原理,找到了制备AlTiC中间合金的一种新工艺。合成的AlTiC中间合金含有大量细小的TiC相及少量粗大的条状Al3Ti相,它具有优异的细化αAl晶粒的性能。TiC相质点团是αAl有效的异质结晶核心。
Based on ClausiusClapeyron equation, a new technology to prepare AlTiC master alloys was developed. Synthesized AlTiC master alloys containing a number of fine TiC particles and a few Al3Ti flakes possess excellent grain refining properties on aluminium. The clusters of TiC particles are effective nuclei of αAl, which is attributed to physical and chemical roles of depressions on the clusters.
