Equivolume composites of melt-spun Tb_(0.5)Dy_(0.5)Fe_(2) in an Fe matrix have been consolidated by hot pressing over a range of temperatures. We find that both the magnetic field dependence of the magnetostriction λ(H) and the torque response R_(τ) of these materials in a sensor configuration deperid strongly on the consolidation temperature. As the hot press temperature increases, λ(H) becomes sharper, generating higher strains at lower applied fields, higher values of the maximum slope dλ/dH, and more nearly saturated λ(H) at the maximum applied field of 19 kOe. These changes in magnetostriction are closely correlated with the observed response of the composites in a torque test. For a composite hot pressed at 755℃ we observe R_(τ)=6.3 G/100 ppm, a value which is twice that obtained for material consolidated at 550℃ and nearly a factor of three greater than the response of maraging steel.
