Abstract Nanostructured Fe-Co-Mn-Ti-B alloyed powder samples were prepared by mechanical alloying. The structural and magnetic properties are investigated by using x-ray diffraction, scanning electron microscopy, transmission electron microscopy, electron dispersive x-ray spectroscopy and also vibrating sample magnetometer. After 80 h of milling time, the grain size attains the lowest value about 30 nm. The coercivity values show almost an increasing trend up to ending stage of milling time. The magnetic characterizations of annealed milled sample for 100 h milling time at 900 °C demonstrate low coercivity (~33 Oe) and relatively high saturation magnetization (~138 emu/g) values.

纳米结构的富铁 (Fe-Co)70 Mn10 Ti10 B10 机械合金粉末：合成和表征研究

摘要 通过机械合金化制备了纳米结构的Fe-Co-Mn-Ti-B合金粉末样品。通过使用 X 射线衍射、扫描电子显微镜、透射电子显微镜、电子色散 X 射线光谱以及振动样品磁强计来研究结构和磁性。球磨时间 80 小时后，晶粒尺寸达到最低值约 30 nm。直到铣削时间的结束阶段，矫顽力值几乎显示出增加的趋势。在 900 °C 下经过 100 小时研磨时间的退火研磨样品的磁性特征表明，矫顽力较低（~33 Oe）和相对较高的饱和磁化强度（~138 emu/g）值。
