Abstract :
Amorphous metallic Fe78Si9B13 fibers, 50 μm in diameter, produced by the melt extraction method, have been studied in the as-quenched state and after furnace annealing at 455°C and 480°C for times between 0.5 min and 50 min. Measurements of the M-H loops and field dependence of Young´s modulus have shown that they behave in a way very like that of amorphous wires. The minimum coercivity of 3 A/m is greater than that found in wires, and the minimum Young´s modulus (~0.45 times the saturation value) is greater. It is suggested that the core-shell domain model applies in the as-quenched state and that stress relief followed by surface crystallization dominate the anisotropy
