受(Ti，Al)N合金化合物在涂层中应用的激励，利用相图计算(CALPHAD)技术分析了Ti-Al-N三元相图。建立了Ti-Al-N三元系的等温截面，并与文献实验结果进行了比较。Ti-Al-N三元系及相关的Ti-N和Al-N二元系的热力学参数取自文献，而Ti-Al二元系的热力学参数则根据三元相平衡和二元相平衡进行调整。计算结果与实验数据的一致性表明，考虑到三元热力学关系，有必要对相关双星的热力学参数进行调整。(C)2008年，北京科技大学。版权所有。
Motivated by the application of (Ti, Al)N alloy compound in the coating layer, the ternary phase diagram of Ti-Al-N was analyzed by the calculation of the phase diagram (CALPHAD) technique. The isothermal sections of the Ti-Al-N ternary system were constructed and compared with the literature experimental results. The thermodynamic parameters of the Ti-Al-N ternary system and the related Ti-N and Al-N binary systems were adopted from literatures, whereas, those of the Ti-Al binary from the literatures were adjusted according to both the ternary and the binary phase equilibria. The consistency between the calculated results and the experimental data shows that considering the ternary thermodynamic relationship, the adjustments to the thermodynamic parameters of the related binaries are necessary.
