摘要
In the view of crystallization activation energy of amorphous alloy, the mechanism of coarse grain in annealed Sm 5Fe 80Cu 1Si 5B 3C 2.5Zr 3.5 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 Sm 5Fe 80Cu 1Si 5B 3C 2.5Zr 3.5 amorphous alloy, which is helpful for forming α-Fe phase grains; and it is not large for Sm 2Fe 17C x phase.
