摘要 采用规则溶液模型计算了Ａｌ－Ｔｉ系几个典型相的自由能──成分曲线。对不同温度下自由能──成分曲线的分析表明，采用这种模型可以解释高能球磨时，由Ａｌ，Ｔｉ金属混合物及ＡｌＴｉ金属间化合物向非晶的转变及非晶化的成分区间。 The free energy-composition curves of several typical phases in Al-Ti system was calculated according to a model of regular solution. From the analysis to the free energy-composition curves at different temperature, it shows that this calculation can approximately explain the transformation of the powder mixture of Al and Ti to amorphous and the composition range of amorphization in Al-Ti system.
