  • Effect of diffusion induced recrystallization(DIR) on mechanical properties of hot-pressed TiC was in-vestigated. The TiC specimen was electroplated with Cr and then heat-treated at 1550. Through the DIR process a new set of (Ti, Cr) C mixed carbide grains with uniform and small size was formed at the surface. As a consequence the scattering in fracture strength decreased and the toughness increased.

  • To evaluate the corrosion behavior of reaction bonded silicon carbides, corrosion test was studied for various corrosive environments. Corrosion test for reaction bonded silicon carbides was conducted at 900$^{\circ}C$ under four different gas atmospehres ; air, So2-air, Cl2-O2-Ar, Cl2-N2 and investigated these samples using weight loss, bending strength, XRD, optical micrographs and EDS respectively.
