Effects of Cycle Treatment on Microstructure,Crystallization and Magnetic Properties of Fe-based Amorphous Alloy
The effects of deep cryogenic cycle treatment,annealing at 473 K cycle treatment and cold-hot cycle treatment on the microstructure,magnetic properties and crystallization process of Fe68Ni1Al5Ga2P9.65B4.6Si3C6.75 amorphous alloys were studied by XRD,DSC and TEM. The results show that samples are still amorphous after different cycle treatment. Struture relaxstion occurs and the microstructure changes. But compared to as-quenched samples,the glass transition temperature,crystallization temperature and crystallization peak temperature have same changes. After annealing crystallization,there are some obvious differences in the variety,the amount and size of crystallization. The statistics of magnetic properties show that it has a little elevation compared to as-quenched samples.
