The study presents the results of microstructural examinations of the Ni-Al-C alloy forming a natural Ni₃Al/C composite, in which the precipitates of graphite are acting as a lubricating, slip phase. Different forms of graphite were described, starting with the fibrous shapes and ending in spheroidal forms, identical with the spheroidal graphite present in cast iron. The morphologies of graphite precipitates in the Ni₃Al phase were compared to similar precipitates observed in ferrous alloys with high carbon content.
