【24h】Effect of Stress Annealing on Galfenol and Alfenol Magnetostrictive Alloys

机译应力退火对Galfenol和Alfenol磁致伸缩合金的影响

【摘要】Selected Galfenol (Fe_(100-x)Ga_x, x = 6, 12.5, 17, 18.4, 19, 22) and Alfenol (Fe_(81)Al_(19)) alloy rods (~50mm x 6 mm dia.) were annealed under compressive stresses up to 219 MPa at temperatures ranging from 100℃ to 700℃ for periods of 10 to 100 minutes. Because of the magnetostriction of the alloys, these heat treatments build in various degrees of uniaxial magnetic anisotropy depending upon annealing stress, annealing temperature, and alloy composition. This built-in uniaxial magnetic anisotropy has the effect of extending the high power capability of these alloys to operate under both tensile as well as compressive loads.
