Abstract
A method for manufacturing rare earth-iron magnetostrictive materials such as Tb.sub.x Dy.sub.1-x Fe.sub.2-w wherein 0.20.ltoreq.x.ltoreq.1.00 and 0.ltoreq.w.ltoreq.0.20. Rare earth and iron raw materials are continuously fed into a plasma arc melting furnace having a plasma arc torch and a water-cooled bottomless elongated mold located beneath the torch. The raw materials are melted together by plasma flames to form a pool of a molten alloy at the top of the mold. Heat is removed from the melt by water cooling through the mold, thereby causing the melt to solidify progressively from the bottom thereof. The solidified body is continuously pulled down in the mold.
