Abstract:In the view of crystallization activation energy of amorphous alloy, the mechanism of coarse grain in annealed Sm5Fe80Cu1Si5B3C2.5Zr3.5 amorphous alloy was analyzed. It reveals the effect of preannealing on the process crystallization. The results show that preannealing can be used to change the crystallization behavior of the α-Fe phase in the Sm5Fe80Cu1Si5B3C2.5Zr3.5 amorphous alloy, which is helpful for forming α-Fe phase grains; and it is not large for Sm2Fe17Cx phase.
Key words: Sm5Fe80Cu1Si5B3C2.5Zr3.5 amorphous alloy; preannealing; crystallization
