摘要
通过 X 射线粉末衍射、配备能量色散 X 射线光谱的扫描电子显微镜和差热分析,研究了 R 2Fe14B-Ce2Fe14B (R = Nd, Pr) 伪二元体系的相关系。X 射线粉末衍射结果表明,R 2Fe14B-Ce2Fe14B (R = Nd, Pr) 伪二元体系中形成了连续固溶体,所有 (R , Ce)2Fe14B 固溶体都属于空间群为 P42/mnm 的四方结构。随着 Ce 含量的增加,(R, Ce)2Fe14B (R = Nd, Pr) 固溶体的晶格参数 a、c 和包晶反应温度呈线性下降,晶胞体积 V 呈回归线变化。根据 X 射线粉末衍射结果和差热分析数据,建立了 R 2Fe14B-Ce2Fe14B (R = Nd, Pr) 体系的准二元相图。
The quasi-binary phase diagrams of R
2Fe14B–Ce2Fe14B (R = Nd, Pr) systems
The phase relations of the R
2Fe14B–Ce2Fe14B (R = Nd, Pr) pseudobinary systems have been investigated by using X-ray powder diffraction, scanning electron microscopy equipped with energy dispersive X-ray spectroscopy and differential thermal analysis. The X-ray powder diffraction results show that continuous solid solutions were formed in this R
2Fe14B–Ce2Fe14B (R = Nd, Pr) pseudobinary systems, and all (R
, Ce)2Fe14B solid solutions belong to the tetragonal structure with space group P42/mnm. With the increase in Ce content, the lattice parameters a, c, the peritectic reaction temperatures of the (R, Ce)2Fe14B (R = Nd, Pr) solid solutions decrease linearly, and the cell volume V varies in the form of the regression line. Based on the X-ray powder diffraction results and differential thermal analysis data, the quasi-binary phase diagrams of the R
2Fe14B–Ce2Fe14B (R = Nd, Pr) systems have been established.
