| 摘 要： | 采用电弧式熔体快淬/吸铸技术，制备了不同成分的Ni-Nd-B试样，借助X射线衍射、扫描电子显微镜、热分析法、静态磁性测试仪等手段进行了分析。研究发现，用电弧式熔体快淬/吸铸技术可以较成功制备系列直径6 mm的Ni-Nd-B大块非晶，且满足深度共晶成分试样表，表现出较理想的非晶形成能力。Ni4NdB材料具有约79.13 ℃的过冷度，Ni13Nd3B2材料具有约69.37 ℃的过冷度；Ni，Nd成分微量变化引起材料较明显的晶化趋向。此外，Ni，Nd成分微量变化导致材料矫顽力、饱和磁化强度减小。

| Abstract: | Ni-Nd-B samples were prepared by arc-type melt-spinning/suction casting techniques, and then were analyzed by X-ray diffraction, scanning electron microscopy and differential thermal analyses and with static magnetic tester. The results show that 6 mm-diameter bulk amorphous samples have been prepared, which conform with the depth eutectic theory and show relatively ideal glass forming ability. The undercooling temperatures of Ni4NdB and Ni13Nd3B2 are 79.13 ℃ and 69.37 ℃, respectively. The trace changes of Ni, Nd compositions cause evident crystallization of materials, and they also lead to the decrease in material coercivity and saturation magnetization. |
