Abstract:

Graphites in Ni-C and Fe-C alloys are flaky and considered to be anomalous eutectic alloys. It is of interest to compare the process of solidification of Ni-C alloy with that of Fe-C alloy, because the former is a simple binary alloy and the latter is a more complicated system with the transformation in the solid state. The Authors discovered that the graphites in Ni-C alloy were isolated and the Ni phase had not so deep grooves at the solid-liquid interface as the austenite in Fe-C alloy. Then, the growth mechanism accompanied by nucleation of graphites was considered. Nucleation in Ni-C alloy was investigated and the possibility of this mechanism was considered. The Ni phase at the solid-liquid interface had deep grooves by additions of 0.1∼0.3%S.
