Powder metallurgical techniques were used to prepare high-density rare-earth iron Laves phase-based magnetostrictive alloys. The rare-earth content of the alloys must be in excess of the stoichiometric composition in order to prevent the formation of oxygen-stabilized intermetallic compounds. Solid-state sintering leads to low-density products. High density can be achieved by employing a liquid-phase sintering approach. The magnetostrictive properties of the sintered products are comparable to those reported on cast samples. 5 figures.
