Abstract: The MC carbides which are precipitated during the freezing of most superalloys are very stable chemical compounds, as are the equivalent nitrides. The latter have been shown to persist through melting and casting processes when the nitrogen levels are above the nitride saturation solubility, but it is not clear whether or not the MC carbides can behave in the same way when exposed to liquids containing carbon at less than the carbide solubility limit. This study was directed towards defining this situation. A …
