Abstract

The article presents the results of a study of the dynamics of structure formation in the ceramic–metal material TiC–CoCrFeNiCu with a high-entropy binder in the self-propagating high-temperature synthesis (SHS) mode. The studies were carried out in situ using dynamic X-ray and synchrotron radiation diffraction (“diffraction cinema”). It was shown that these two methods complement each other and allow one to obtain a fairly complete picture of the evolution of phase composition and crystal structure of multicomponent systems during SHS. The results obtained demonstrate new possibilities for direct experimental study of structure formation in high-entropy materials.

SHS过程中TiC-CoCrFeNiCu体系相变的时间分辨x射线衍射研究

本文介绍了在自传播高温合成（SHS）模式下，高熵结合剂对陶瓷-金属材料TiC-CoCrFeNiCu结构形成动力学的研究结果。这些研究是利用动态x射线和同步辐射衍射（“衍射影院”）在现场进行的。结果表明，这两种方法相辅相成，可以较全面地了解多组分体系在SHS过程中相组成和晶体结构的演变过程。所得结果为高熵材料结构形成的直接实验研究提供了新的可能性。

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.
