通过对Ｎｄ２Ｆｅ１４Ｂ四方相单胞分析，确定其结构因数，进而建立了稀土永磁合金直接比较法定量相分析计算程序。在对单相计算结果与实验值取得一致的基础上，对α－Ｆｅ／Ｎｄ２Ｆｅ１４Ｂ双相稀土永磁合金进行了定量相含量测算和分析。
Through the analysis of tetragonal mononuclear cells of Nd2Fe14B, the structural factors were determined, and then the procedure of quantitative phase analysis calculation of direct comparison of rare earth permanent magnet alloys was established. Based on the agreement between single-phase calculation and experimental data, the quantitative phase content of α-Fe / Nd2Fe14B dual-phase rare earth permanent magnet alloy was calculated and analyzed.
