抄録

Amorphous Fe₇₅Ga₅P₁₂C₄B₄ alloy rods were prepared in the diameter range up to 1.0 mm by copper mold casting. The glass transition temperature (T_g), supercooled liquid region (ΔT_x(=T_x−T_g)) and reduced glass transition temperature (T_g⁄T_m) of the amorphous alloy rods are 731 K, 37 K and 0.61, respectively, in agreement with the results for the corresponding melt-spun amorphous alloy ribbon. The Curie temperature (T_c), saturated magnetization (I_s), coercive force (H_c) and saturated magnetostriction (λ_s) of the melt-spun amorphous ribbon are 622 K, 1.28 T, 1.6 A/m and 19.6×10⁻⁶, respectively, in which the T_c and I_s are nearly the same as those for the amorphous alloy rod with a diameter of 0.5 mm. The simultaneous achievement of high T_g⁄T_m, large ΔT_x and good soft magnetic properties for the simple Fe-based alloy system is promising for the future development of bulk amorphous Fe-based soft magnetic alloys.
