oriented rods of TbDyFe giant magnetostrictive alloys have been prepared with the help of the zone melting direc-tional solidification technique with a high temperature gradient. To acquire optimal magnetostrictive properties at low magnetic field,the TbDyFe alloys have been heat-treated at different temperatures and cooled at different rates. The relationships between the proc-ess of the heat treatment, microstructure, defects, and magnetostrictive properties of the TbDyFe materials have been studied.
