We have fabricated novel magnetostrictive composites consisting of SmFe2 embedded in an Fe or Al matrix which feature high magnetostriction and good mechanical strength. Hot pressed composites of 50% SmFe2/50% Fe or Al by volume have magnetostrictive strains parallel to the applied magnetic field, λ(parallel), between −280 and −440 ppm when consolidated at 610 (Fe) or 540 °C (Al). One unique feature of this work is the production of the magnetostrictive SmFe2 component by melt spinning; ribbon-based composites with Al combine significant magnetic coercivity, Hci=3 kOe, with high magnetostriction (λ(parallel)=−280 ppm). Unlike their brittle SmFe2 parent materials, the composites are easily machinable. © 1997 American Institute of Physics.
