The interdiffusion of HfC and TiC during hot pressing was investigated using concentration profiles obtained via EDS in a SEM. The results were interpreted using the Boltzmann-Matano method and the integrals and derivatives were determined via numerical means. The microstructural evolution of two materials with different HfC/TiC was then explained in terms of the rate of material movement.
