Abstract: Directional solidification process of Nd17Fe75B8alloy is studied experimentally. It is found that the Nd2Fe14B matrix crystallized directly from the melt and grows directlynally in dendrite formation. The preferred growth direction of the dendrite is [100], perpendicular to its easy magnetication direction [001].

Key words: preferred growth direction, direction of easy magnetization, directional solidification
