【Abstract】 In the view of crystallization activation energy of amorphous alloy, the mechanism of coarse grain in annealed Pr Fe B amorphous alloy was analyzed. It indicates the effect of Zr in the process crystallization. Experimental results show that Zr can be used to change the crystallization behavior of the α Fe phase in the Pr Fe B amorphous alloy, which is helpful for forming α Fe phases of fine grain size.更多还原
