主　　题：TbDyFe heat treatment microstructure defect magnetostriction 

摘      要：〈110〉 oriented rods of TbDyFe giant magnetostrictive alloys have been prepared with the help of the zone melting directional 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. 2008 University of Science and Technology Beijing.
