Abstract—The structure of hardening niobium carbide particles in a cast heat-resistant alloy based on the Fe–Cr–Ni–C system modified with Nb and Ti is studied by means of optical and electron microscopy. It is established that the particles of niobium carbide in the structure of the cast alloy can be considered as multiphase polycrystalline clusters that are heterogeneous in chemical composition and crystalline structure. Possible reasons for a complicated polycrystalline structure of niobium carbide particles are presented.
