Abstract

Nd 40Fe 30Al 10Co 15B 5 alloys were fabricated by high energy ball milling method under various conditions. Microstructure of the alloys was investigated by X-ray diffraction and electron microscopy techniques. Magnetic properties were characterized by hysteresis and thermomagnetic measurements. The high coercive fields up to 2.36 T have been observed on the samples consisting of Nd 2(Fe,Co,Al) 14B, Nd 6(Fe,Co,Al) 14 and Nd crystallites imbedded in a residual amorphous matrix.
