通过分析扩散对，研究了Ti-Al-Mo β固溶体在1523 K（1250℃）温度下的相互扩散。从用误差函数展开（ERFEX）解析表示的浓度分布中，分别用Whittle-Green和广义Hall方法提取三元间扩散系数和杂质扩散系数。对比了5种Ti-Al- x （Co, Cr, Fe, Mo， V）三元体的扩散，发现Ti-Al-Mo与Ti-Al-（Cr， V）相似，而Ti-Al-(Co, Fe)主要为间隙性质。
Interdiffusion in Ti-Al-Mo beta solid solution was investigated at 1523 K (1250 A degrees C) by analyzing diffusion couples. From the concentration profiles analytically represented by error function expansion (ERFEX), the ternary interdiffusion coefficients and impurity diffusivity were extracted by the Whittle-Green and generalized Hall methods. A comparison of the diffusion in five Ti-Al-X (Co, Cr, Fe, Mo, and V) ternaries reveals Ti-Al-Mo is comparably like Ti-Al-(Cr, V) while Ti-Al-(Co, Fe) are predominantly of interstitial nature.
