摘要：

We present a model for the development of crystallographic texture by hot-deformation in NdFeB magnets produced by rapid solidification. Favorably oriented grains, with their c-axis parallel to the compression axis, grow by mass transport through a Nd-rich liquid grain boundary phase, forming large platelet grains. The driving force is the elastic energy difference between grains with c-axes making different angles with the compression axis. Numerical calculations based on the known properties and conditions of these materials are consistent with a liquid diffusion model.
