Abstract
TiB2–Ti metal–ceramic composites were produced by forced SHS compaction. The influence of superstoichiometric amount of Ti (6–20 wt %) relative to TiB2 on the regularities of combustion and phase composition/structure formation of TiB2–Ti composites was studied. It was shown that the phase composition of composites is inconsistent with the Ti–B phase diagram. The microhardness of composites was determined to drop from 34 to 18 GPa with increasing the binder content. Cutting properties of composites were evaluated.
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.
