Abstract

Microstructure and magnetic properties of Fe64 Ni1 Al4.5 Cu0.5 Ga2 P9.65 B9.6 Si3 C5.75 amorphous alloy after magnetic pulse treatment and crystallization annealing were investigated by XRD and VSM.The XRD results show that after magnetic pulse treatment

the type and crystal volume fraction of precipitates in the alloy after crystallization are increased with decreasing in the grain size

and grain refinement occurs.The VSM results reveal that the Msof the alloy is increased

however

the residual magnetization Mr

the remanence ratio Mr/Msand the coercive force Hcare decreased

so the soft magnetic properties of the alloy are improved.
