摘要：
Structure and soft magnetic properties for the bulk Fe70Al5Ga2P9.65C5.75B4.6Si3 glassy alloy prepared by pulse current sintering with uniaxial pressure were investigated. The sample consolidated in the temperature range of the supercooled liquid region consisted only of amorphous phase and had a very high relative density of 99%. The flux density at the applied magnetic field of 800 A/m, maximum permeability, coercive force and relative permeability at 1 kHz for the sample sintered at 703 K in as-made state are 1.1 T, 7600, 12 A/m and 1700 respectively. The soft magnetic properties of the sintered bulk Fe-based glassy alloy were much superior to the other magnetic materials of consolidated amorphous powders. It is concluded that the high relative density and good soft magnetic properties for the bulk Fe-based glassy alloy should depend upon its high structural homogeneity originated from its high deformability, that is based on the viscous flow arisen from the appearance of supercooled liquid region.
