KW–TiC alloy was fabricated through mechanical alloying method and hot rolling process. Compared with KW alloy, the KW–TiC alloy exhibited bending strength of 2500MPa and higher deformation capacity. Both KW–TiC and KW had ductile-to-brittle transition temperature below 250°C. Annealing at 1800°C for 1 hour, no significant equiaxed recrystallization was observed. KW–TiC alloy had the similar structure to KW, but its size was much smaller. The thermal shock resistance of both alloys was characterized by an electron beam facility. Thermal shock tests were conducted at absorbed power densities from 0.44GW/m² to 0.88GW/m². After the tests, the KW–TiC and KW alloys showed different crack morphology. However, the existence of TiC reduced the thermal conductivity of KW–TiC alloy, which resulted in the surface melting.
