Abstract: Growth behavior of Ti-based carbonitride ceramic grains in two high-Mo Ti(C,N)-based cermets with Ni and Ni–20Cr (wt %) binders was investigated during liquid-phase sintering under vacuum at 1410°C, using DSC, XRD, SEM, AEM, and EDS. Grain growth occurred primarily through two-dimensional nucleation and lateral growth. Most significantly, the grain growth kinetics followed the cubic law, which was controlled by the diffusion of dissolved mass through liquid Ni-based binder phase.
