A high-pressure arc furnace has been used to prepare button- and rod-shaped samples of Sm0.86Dy0.14Fey alloys. Sm losses as a result of volatilisation during melting were found to be lower than those encountered when using conventional arc melting techniques, while higher arc currents could be employed leading to more effective melting. The effects of annealing on the microstructures and the magnetomechanical coupling factor, k(33), have also been investigated. X-Ray diffraction and scanning electron microscopy analysis indicated that annealing samples at 850 degreesC under vacuum for periods up to 10 h gives a pseudo-single phase microstructure. A double partial zoning technique, followed by annealing, was devised to prepare rod samples with high magnetomechanical coupling factors. (C) 2003 Elsevier B.V. All rights reserved.
