在6MPa下用超声气体雾化法制得Nd13Fe80B7粉末研究粒径不同的粉末的形貌及结构阐述了冷却速度是尺寸不同的颗粒具有不同形貌及结构的原因
Nd13Fe80B7 powders were produced by ultrasonic argon atomization at pressure of 6MPa.The particle diameter ranges from 1 to 100μm, and the average powder diameter defined by the cumulative weight fraction of 50pct is about 38μm. The morphologies and micro
