Abstract

The columnar-grained structure induced by directional solidification was beneficial to improve the deformability of Fe 83Ga 17 alloy. Fe 83Ga 17 wires with diameter of 0.5∼0.9 mm were prepared successfully by hot rotary swaging and warm drawing from the directional solidified rods. The magnetostriction and microstructure of the as-drawn and the annealed Fe 83Ga 17 wires with diameter of 0.6 mm were investigated. Results demonstrated that the magnetostriction of Fe 83Ga 17 wires depended on the microstructure and the fiber texture, which were controlled by heat treatment process. The maximum magnetostriction of 160 ppm was detected in the annealed wire, which has the ideal <100> fiber texture. The phase mixture of A2 containing heterogeneous modified-DO 3 phase has beneficial effect on magnetostriction.
