Abstract
Using mathematical modeling the kinetics of the rim-core structure formation of TiC grains in an isothermal liquid-phase sintering of TiC–Ni hard alloy, doped with a transition metal carbide has been investigated. The algorithm that has been used to study the nature of the concentration distribution of the diffusant in a TiC grain allows for the structural characteristics of the alloy; diffusion coefficients of alloying additives in the metal melt and a grain, boundary solubility of the diffusant in the binder, and its concentration in the alloy as well as the sintering temperature and time.
