Magnetic anisotropy of a selective laser melted Fe-Si-B alloy

Abstract

Selective laser melted 1CP alloy sample was obtained. Sample is partially amorphous, otherwise it consist of α–Fe(Si) and ordered Fe3Si. In the direction parallel to the axis of the sample the coercivity is slightly lower than in the perpendicular direction and the saturation magnetization is greater. Magnetic anisotropy in sample is not weakened by held annealing: heating of 10 C°/min to 440C°, holding for 30 minutes, followed air cooling. After heat treatment coercivity in the direction parallel to the sample axis decreased from 50 Oe to 38 Oe (34%).
