In this paper, the relationship between composition and crystallization temperature of Fe-base amorphous alloys are investigated systematically. Among 95 Fe-base amorphous alloys, the crystallization temperatures of about 85% of them are in the range of 700-825 K, Tcr/Tm≈1/2 (0.42-0.62), and conform to Sakka's principle The crystallization temperature of Fe1-x Bx-ySiy is greater than that of Fe1-xBx and the later greater than that of Fe1-xBx-yPy in turn. Those mentioned above are discussed with reference to the composition, phase diagrams, machanism of the crystallization, diffusion and the relationship between the crystallization temperature and the average electronic concentration (e/a).
