Synthesis of TiZrHfVNb Multi-Principal Element Alloy using SHS Hydrides by “Hydride Cycle” Method
Finding new energy effective methods for the production of refractory multi-principal element alloys (MPEAs) is a challenge for rapidly developing MPEA materials science. Formation of equimolar TiZrHfVNb MPEA and evaluation of alloy potential for use as hydrogen storage material were investigated. In this study, we demonstrated, for the first time to the best of our knowledge, that MPEA can be produced using SHS hydrides as precursor materials by “Hydride Cycle” (HC) method. The hydrogenation of obtained alloy by self-propagating high-temperature synthesis (SHS) method was studied. Crystal structure, surface microstructure, chemical composition, and thermal stability of synthesized materials were studied. It was shown that two-phase (α + β) alloy was synthesized. As a result of the SHS hydrogenation process, TiZrHfVNb alloy absorbed 1.8 wt % of hydrogen.
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.
