The authors present a model for the development of crystallographic texture by hot deformation in NdFeB magnets produced by rapid solidification. Favourably 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.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
