Phenomenon of ignition and explosion of high-entropy alloys of systems Ti-Zr-Hf-Ni-Cu, Ti-Zr-Hf-Ni-Cu-Co under quasi-static compression.

This article explores the phenomenon of ignition and explosion in high-entropy alloys (HEAs) under compression. The study focuses on specific HEAs in the Ti-Zr-Hf-Ni-Cu and Ti-Zr-Hf-Ni-Cu-Co systems, which exhibit high strength and ductility. The authors propose a model to explain the ignition and explosion, which occurs when certain critical levels of strength and ductility are reached. The article provides detailed information on the materials and methods used in the study, as well as the chemical composition and physical properties of the alloys. Additionally, the text discusses the mechanical testing and failure process of a specific alloy, highlighting the factors that contribute to ignition and explosive failure. The research was funded by the National Academy of Sciences of Ukraine and includes a list of references to related scientific articles and papers. [Extracted from the article]
