%X The single-phase nanocrystalline Pr2Fe14B magnets composed of cubic-shaped and irregular-shaped grains is built. The magnetic hysteresis loops are simulated by micromagnetism finite element method. The remanence, coercivity and maximum energy product decrease with deteriorated grain alignment. Attributed to strong intergrain exchange coupling (IGEC), the variation of magnetic proper ties with alignment degree is significantly affected by the average grain size i n nanocrystalline magnets. The investigation shows the increase of coercivity wi th improved grain alignment in nanocrystalline magnets, which is completely diff erent from the phenomena in sintered magnets.
