Metastable phases in Co70B20Si5Fe4Mo1 alloy fabricated by non-equilibrium processes
In this study, the fabrication and magnetic characterization of amorphous/nanocrystalline Co70B20Si5Fe4Mo1 alloy by means of mechanical alloying (MA) and melt spinning (MS) process have been investigated. The produced samples were characterized using X-ray diffraction (XRD), differential scanning ca...

| description | In this study, the fabrication and magnetic characterization of amorphous/nanocrystalline Co70B20Si5Fe4Mo1 alloy by means of mechanical alloying (MA) and melt spinning (MS) process have been investigated. The produced samples were characterized using X-ray diffraction (XRD), differential scanning calorimetry (DSC), vibrating sample magnetometer (VSM) and scanning electron microscopy (SEM). The results showed that fully amorphous phase can only be formed by means of melt spinning processes, and the final product during mechanical alloying is the combination of nanocrystalline (CoHCP+CoFCC (about 10nm)) and amorphous phases. The produced melt spun amorphous ribbons exhibit soft magnetic properties with the coercivity and saturation of magnetization in the range of 1.5–2Oe and 90–120emu/g, respectively.
