简介 This invention provides an improvement to magnetostrictive torque sensors giving an output signal indicative of the torque applied about the axis of a shaft where the shaft includes a magnetostrictive ring, attached to or formed as a part of the shaft so that the torque applied to the shaft is applied proportionally to the ring, and the ring consists essentially of novel composites consisting of magnetically hard and highly magnetostrictive rare earth (iron)2 binary compound particles embedded in Cu, Fe, or other suitable metals.
