Abstract

In this study, Nanocrystalline Nd8Pr2Fe79-xCo5B6Alx (x= 0, 1, 2, 3) magnets were prepared by mechanical alloying method and respective heat treatment in a constant time and temperature. Afterward, the effects of the Al addition on the microstructure and magnetic properties of Nd-Fe-Co-B alloy were studied. The changes in the nanostructure and magnetic properties were examined by X-Ray diffraction (XRD), combined with Field Emission Scanning electron microscopy (FeSEM) and vibrating sample magnetometer (VSM). Addition of Al was found to be effective for improving the coercivity parameter and the hysteresis squareness in Nd-Fe-Co-B magnets without decreasing much the remanent magnetization.
