稀土双相永磁合金X射线无标定量相分析

X ray None standard Quantitative Phase Analysis on Rare earth Dual phase Permanent Magnetic Alloys

通过对Ｎｄ２Ｆｅ１４Ｂ四方相单胞分析，确定其各原子坐标，进而采用计算Ｋ值直接对比法，建立了双相永磁合金相分析计算程序。在对单相计算结果与实验值取得一致的基础上，对α－Ｆｅ／Ｎｄ２Ｆｅ１４Ｂ实验合金进行了相含量测算和分析。

The coordinate of every atom of tetragond Nd 2Fe 14 B phase is determined by analyzing its crystal cell. Then, the computer program of phase analysis on α-Fe/Nd 2Fe 14 B dualphase permanent magnetic alloys is established by adopting calclate K value directly comparing method. On the basis of calculate results on single phase case being consistent with experimental values,the phase analysis on lab prepared alloys are carried out.
