Fig.15 Experimental information on the solubility of graphite in the Ni-rich fee<br />

phase in the Ni-Ti-C system at various temperatures. Comparison is<br />

made with calculations of the fee + graphite and fee + graphite + TiC<br />

equilibria, using Ni-C from Lee [92Lee], Ni-Ti from Bellen [96Bel] and<br />

Ti-C from Jonsson [96bJon].<br />
