Abstract
The solidification process of Fe-C alloys, and the effects of Mg and Si have been reported in the previous papers. In this paper the experiments on the effects of Al and Mn on the solidification process of hypo-eutectic Fe-C system carried out by the same method as before are reported. The results of the thermal analysis and the microscopic examination lead to the following conclusions; The effect of Al on the solidification process of Fe-C alloys is quite similer to that of Si, but Mn acts reversely and results in a characteristic structure as the Mn content increases.
