摘　　要：采用深共晶法对非晶合金Ni-Nd-B的配方进行设计,设计后的非晶合金配方将具有较高的非晶形成能力。利用铜模吸铸方法得到尺寸为Φ6 mm×30 mm的Ni-Nd-B非晶棒材,并采用XRD、DTA、SEM对非晶棒材进行表征。结果发现,此材料的约化玻璃转变温度Trg为0.56,这表明通过设计的合金材料有很高的非晶形成能力。在Ni-Nd-B材料中Ni、Nd成分的微量变化,将导致合金趋向于形成三元结晶相,这主要是由于深度共晶配料引起的。The formulation of Ni-Nd-B amorphous alloys was designed by deep eutectic methods, the well-disigned amorphous alloys formula possesses high amorphous forming ability. After that the bulk of Ni-Nd-B amorphous bar with a dimensions of 6 mmx30 nun was obtained by using copper mould suction casting, and characterized by means of XRD, DTA and SEM. A high reduced glass transition temperature Trg of 0.56 have been obtained in bulk amorphous, it means these engineered alloys showed a high amorphous forming ability. The alloys tend to torm ternary crystalline phase with the subtle variation of Ni, Nd in Ni-Nd-B, this probably caused by deep eutectic compositions.
