Abstract

Fabrication of nanocrystalline Co-B-Si-Fe-Mo magnetic alloys by means of mechanical alloying was the goal of this study. In this regard, different powder mixtures containing Co70B30−x Si x (x = 10, 15, 20) and Co70B20Si5Fe5−x Mo x (x = 0, 2.5, 5) (at.%) were mechanically milled in a planetary ball mill for different periods of time. The produced samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). The produced alloys exhibit magnetic properties with the saturation of magnetization and coercivity in the range of 30–260 Oe and 100–180 emu/g, respectively. The highest saturation of magnetization and the lowest coercivity appear in alloys with higher B content. Moreover, Fe element has a suitable effect and Mo element has a destructive effect on soft magnetic properties of Co70B20Si5Fe5−x Mo x alloys.
