Abstract

Both the coercive force and the saturation magnetostriction of rapidly solidified Fe49Co49V2 thin ribbons increase with increases in the circumferential velocity during the melt-spinning process because of The formation of a preferred orientation texture. Fe 49Co49V2 pellets produced by spark plasma sintering of the powder prepared by milling the rapidly solidified ribbon also exhibit a coercive force higher than those of ordinary alloy ingot. In particular, the coercive force significantly increases after the milling process, reaching a maximum value of 86 Oe, or 10 times higher than an ingot with same composition. The change in the magnetic properties results from the effects of rapid solidification and of the stress induced during the milling process. The magnetostriction of a pellet is slightly smaller than the value for the ingot and is comparable to the value of rapidly solidified ribbons produced by low circumferential velocities.
