研究了轮速对熔纺Nd1.2Fe10.5Mo1.5薄带的相组成和显微组织的影响。结果发现，轮速为10 m/s时即可得到Nd(Fe,Mo)(12)相，轮速高于10 m/s时则形成TbCu7型Nd(Fe,Mo)(7)相。非晶相以 65 m/s 的速度实现。相的平均晶粒尺寸随着轮速的增加而线性减小。由以 65 m/s 淬火的退火带材获得的 Nd(Fe,Mo)(12)N-1.0 氮化物表现出比以 10 m/s 淬火的带材获得的矫顽力高得多，这是由于前者带材的晶粒尺寸较小。 (c) 2011 Elsevier B.V. 保留所有权利。
The effect of wheel speed on the phase compositions and microstructures of melt-spun Nd1.2Fe10.5Mo1.5 ribbon was investigated. It is found that the Nd(Fe,Mo)(12) phase can be obtained at the wheel speed of 10 m/s, and TbCu7-type Nd(Fe,Mo)(7) phase is formed with the wheel speed higher than 10 m/s. The amorphous phase is achieved at 65 m/s. The average grain size of phases decreases linearly with increasing wheel speed. The Nd(Fe,Mo)(12)N-1.0 nitride obtained from annealed ribbons quenched at 65 m/s shows a coercivity much higher than that from the ribbons quenched at 10 m/s, which is due to the smaller grain size in the former ribbons.
