The Nd60Fe20Al8Co10B2 alloy was prepared by suction casting of the molten alloy into a copper mold under argon atmosphere.The micro-structural and magnetic property changes in the Nd60Fe20Al8Co10B2 alloy during crystallization were investigated by X-ray diffraction(XRD),differential scanning calorimetry(DSC),scanning electron microscope(SEM)and the vibrating sample magnetometer(VSM).The precipitation and Nd-rich and Fe-rich phases have no significant effect on the intrinsic coercitity for Nd60Fe20Al8Co10B2 alloy annealed below 723 K.However,the growth of Fe-rich phase decreases the saturate magnetization and remanence of the alloy.The hard magnetic behavior is disappeared when the alloy is fully crystallized.
