An inflection hehaviour was revealed during isothermal annealing under the observation of transition of the coercivity of Fe-Si-B amorphous alloys during local crystallization.It may be interpreted by the transition of α-Fe grain precipitated from single to multiple domain, Thus,the theoretical expression of H_0-t_a may be derived.The plot of expression H_0-t_a calcu- lated well represents the feature of the experimental curve.
