Abstract
Regularities of combustion of Co3O4/Cr2O3/WO3/MoO3/C/Al mixtures with additive of Ti under the action of artificial gravity were studied. At the centrifugal acceleration of more than 40 g, combustion products were obtained as two-layer ingots of target CoTiCrWMoCAl alloy (lower) and Al2O3 slag (upper). Variation in the amount of additive (up to 17 wt %) affected the composition and structure of cast CoTiCrWMoCAl alloy. SHS-produced alloys were characterized by XRD, SEM, and EDS. CoCrWMoCAl alloy containing 5% Ti was used for preparing powder by vacuum induction melting followed by inert gas sputtering. It was shown that the chemical compositions of powder and its precursor are the same.
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.
