Thermal treatment for increasing magnetostrictive response of rare earth-iron alloy rods
Patent
·
OSTI ID:7021689
Magnetostrictive rods formed from rare earth-iron alloys are subjected to a short time heat treatment to increase their magnetostrictive response under compression. The heat treatment is preferably carried out at a temperature of from 900 to 1,000 C for 20 minutes to six hours.
