Abstract
This study examines the influence of mechanical activation (MA) and initial titanium powder properties on forced self-propagating high-temperature synthesis (SHS) compaction of Ti–C mixtures. MA of pure titanium powder substantially elevated its oxygen content from 0.3 to 2.0 wt %, whereas Ti + C mixtures exhibited minimal uptake (∼0.2–0.3 wt %) due to carbon black occlusion of titanium surface defects, enhancing reagent contact while inhibiting atmospheric oxidation. Ignition and combustion temperatures rose with oxygen concentration in titanium, independent of Ti–C interfacial area; however, burning velocity correlated directly with this area, increasing with MA time and declining with surface oxygen levels.
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.
