Abstract: Fe⁷⁰Zr¹⁰B²⁰ magnetic amorphous alloy was prepared by the mechanical alloying method, and its crystallization mechanism was analyzed. The magnetic properties of Fe⁷⁰Zr¹⁰B²⁰ mixed powders during the mechanical alloying and Fe⁷⁰Zr¹⁰B²⁰ amorphous alloy at different heat temperatures were researched. The results show that the Fe⁷⁰Zr¹⁰B²⁰amorphous alloy crystallized in primary crystallization mode. The magnetic properties of Fe⁷⁰Zr¹⁰B²⁰ magnetic amorphous alloy are related with structure, pellet size, stress, defect and other factors.
