【摘要】 首次采用磁性分析法测定Ce在α-Fe中的固溶度。通过测量矫顽力和成分的关系曲线,发现随着Ce含量的增加,矫顽力保持常数;当Ce含量超过某一临界值,矫顽力突然增加,研究发现此临界值即为Ce在α-Fe中的最大固溶度。结果与作者采用其它方法得到的结果一致。更多还原

【Abstract】 The coercive forces of the samples with different contents of Ce in α-Fe were measured by using vibrating sample magnetometer. The results indicated that coercive forces were related closely to cerium content in Fe-Ce alloy. Coercive force kept constant with the increase of cerium content at the beginning. As the cerium content increased beyond a critical value, the coercive force increased abruptly. Based on an elaborate investigation and analysis, the critical value was found to be the maximum solubility of Ce in α-Fe. The result was in good agreement with that obtained by using other methods in our previous work.更多还原
