Sintered Rare Earth--Iron Laves Phase Magnetostrictive Alloy Product and Preparation Thereof

摘要

A sintered rare earth-iron Laves phase magnetostrictive alloy product is characterized by a grain oriented morphology. The grain oriented morphology is obtained by magnetically aligning powder particles of the magnetostrictive alloy prior to sintering. Specifically disclosed are grain oriented sintered compacts of Tb/sub x/Dy/sub 1-x/Fe sub 2 and their method of preparation. The present sintered products have enhanced magnetostricitive properties.
