Al-Mo二元系和Ti-Al-Mo三元系0 ~ 20 at.%热力学描述的再评价进行了钛。新的Al-Mo描述再现了AlMo相的全等熔化，并且计算的相图与富铝区域上的实验数据非常吻合，显示了几个富铝金属间相的形成。新的Al-Mo描述被用作Ti-Al-Mo系统中的组分二元，并且η、β和δ相的热力学参数被重新优化。在0 ~ 20 at.%的范围内，用新的描述方法计算的结果与实验结果吻合得很好。Ti显示了β相从Ti-Mo二元到Al-Mo二元的延伸，几种合金的β相凝固，以及β，Al（8）Mo（3），δ和η相之间在1540 K的过渡反应。(C)2010爱思唯尔有限公司保留所有权利。
A re-assessment of the thermodynamic description of the binary Al-Mo and of the ternary Ti-Al-Mo system from 0 to 20 at.%Ti was performed. The new Al-Mo description reproduces a congruent melting of the AlMo phase and the calculated phase diagram is in excellent agreement with the experimental data on the Al-rich region showing the formation of several Al-rich intermetallic phases. The new Al-Mo description was used as the constituent binary in the Ti-Al-Mo system and the thermodynamic parameters of the eta, beta, and delta phases were re-optimized. Calculations using the new description are in good agreement with experimental work performed in the region from 0 to 20 at.% Ti showing the extension of the beta phase from the Ti-Mo binary to the Al-Mo binary, the beta phase solidification of several alloys, and the transition reaction between the beta, Al(8)Mo(3), delta, and eta phases at 1540 K.
