Abstract
CoCrNi–TiC cermet was synthesized by spark plasma sintering, resulting in the formation of secondary chromium-rich (CoCrNi)3C2 phase during consolidation. The cermet was found to exhibit a markedly enhancement in mechanical properties, achieving a Vickers hardness of 16 320 MPa compared to 2025–2332 MPa for CoCrNi, while preserving a fracture toughness of 8.12–10.60 MPa m1/2. This strengthening effect is directly attributed to the reinforcing role of TiC grains within the composite structure.
期刊介绍:
International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
