Structure formation and properties of NbC-Hadfield steel cermets

The structure and properties of based on NbC cermets with a binder of Hadfield Steel has been studied. The cermets have been produced by the infiltration of NbC skeletons with steel at 1450°C in the argon atmosphere. The resultant materials have two-phase structure, namely, manganese austenite and NbC grains. The optimal complex of mechanical properties has been attained in cermets with the 55–60 vol % concentration of the carbide phase.
