抄録

Nucleation and growth during solidification of the primary austenite were investigated, paying attention to the degree of undercooling for nucleation, the degree of nucleation and the growth morphology of austenite. The experiment was conducted on hypo-eutectic iron of Fe-C system inoculated with ferro-silicon or calcium-silicide and held at the molten state. Inoculation effect and fading phenomenon were observed in the nucleation of graphite eutectic with Fe-Si or Ca-Si addition, in agreement with the previous studies. Nucleation of primary austenite is promoted by adding Ca-Si, but is hindered by adding Fe-Si. Inoculation effect on the solidification of primary austenite differs from that on the graphite eutectic.
