Abstract

Magnetic properties such as magnetization, coercivity, and magnetostriction of rapidly quenched ternary Fe100−x−yAlxSiy (0 ≦ x ≦ 28.3, 0 ≦ y ≦ 10), Fe100−x−yAlxBy, and Fe100−xAlxGey (0 ≦ x ≦ 28.3, 0 ≦ y ≦ 20.4) are investigated. In the FeAlSi system, the alloys near Fe75Al25 composition exhibit relatively soft magnetic properties. In the FeAlB system, amorphous structure is achieved in the range 12 ≦ y ≦ 25 and best soft magnetic properties, Hc = 1.6 A/m, Bs = 1.1 T, μm = 1.4 × 105, Q = 160 μΩ cm are obtained around Fe60Al20B20 composition. In the FeAlGe system, magnetostriction is nearly zero in the composition range 0 ≦ x ≦ 15, 10 ≦ ≦ y ≦ 15. The Fe‐rich alloys in FeAlSi and FeAlGe systems show a high saturation induction above 2.0 T and a small magnetostriction less than 10 × 10−6.
