Abstract

Effects of pulse magnetic field pretreatment on the structure and the crystallization process of amorphous alloy（Fe74Ga2P9.65B4.6Si3C6.75）98Nb2 were investigated by XRD and DSC.Furthermore

the magnetic properties were also analyzed by VSM.The results show that after pulse magnetic field pretreatment

there exists some atomic clusters and a little crystallized phases segregation in samples.When the samples are crystallized

precipitates are increased with the decrease of the average grain size

and the crystallization area is increased with increasing in the processing time.The VSM test results indicate that the coercivity and remanence ratio of the samples are reduced significantly after pulse magnetic field pretreatment

indicating more excellent integrated magnetic properties.
