Abstract A thermodynamic description for the B-Nd-Cr system has been developed on the basis of the constituent binaries and critically reviewed ternary experimental data. The published thermodynamic descriptions for the B-Nd and Nd–Cr binaries were directly used and that for the B–Cr binary was optimized in the present study. The invariant reactions of Liquid↔Bcc1+Bcc2 (1237 K) in the Nd-Cr system, the phase stability of B4CrNd and B6Cr2Nd, the liquidus projection and isothermal section were calculated accordingly based on the currently obtained thermodynamic description and compared with the experimental results. The calculation results are in good agreement with the experimental data.

B-Nd-Cr 系统的热力学评估

摘要 基于组成的二元和严格审查的三元实验数据，开发了 B-Nd-Cr 系统的热力学描述。直接使用已发表的 B-Nd 和 Nd-Cr 二元热力学描述，并在本研究中优化了 B-Cr 二元的热力学描述。根据目前得到的热力学描述计算Liquid↔Bcc1+Bcc2(1237 K)在Nd-Cr体系中的不变反应、B4CrNd和B6Cr2Nd的相稳定性、液相线投影和等温截面，并与实验结果进行比较. 计算结果与实验数据吻合较好。
