| Abstract: | Formation of phase structure for Nd_8Fe_(86)B_6 nanocrystalline alloys at different speed of rapid quenching was studied.The X-ray diffractometry(XRD) and vibrating sample magnetometer(VSM) were performed in order to investigate the structure and the magnetic properties.When speed of rapid quenching was at 18 m/s,the average grain size of Nd_8Fe_(86)B_6 alloy ribbons was uniform,petty and the best magnetic properties were achieved.The average grain size of Nd_8Fe_(86)B_6 alloy ribbons was 24.4 nm and the best magnetic properties of B_r,B_r/B_s,H_c were 0.69 T,0.66 and 296.1 kA/m,respectively. |
