Article Preview

The microstructure evolution during high-temperature deformation at (a) high strain rates and low strains (dynamic densification, shock compression) and (b) low strain rates and high strains (quasi-static densification, superplastic regime) was studied. Off-stoichiometric titanium carbide was selected as a testing system. The results demonstrate that high-temperature deformation in a broad range of strain rates provides means for controlling the microstructure of titanium carbide. By varying deformation conditions, one can obtain materials differing in microstructure and chemical composition, in particular, with equilibrium and nonequilibrium microstructures. Accordingly, the physicochemical properties of such materials are also different.
