Effect of gradient nanostructures on mechanical properties of Ti/AlCoCrFeNi composites

Despite the challenges in engineering applications, the strength, plasticity, and wear resistance of metallic materials still exist, especially at room temperature, where these properties are critical to the performance of the materials. However, there is a certain gap in current research in revealing the mechanism of the effect of high entropy alloys (HEA) and fine grain structure (GNS) on room temperature properties. The aim of this study is to investigate the synergistic effect of HEA particles and GNS and their enhancement on the properties of titanium matrix composites under room temperature conditions. The experimental results showed that with the formation of GNS and the strengthening effect of HEA particles significantly increased the strength and wear resistance of the material. This study provides new insights into the interaction between HEA and GNS at room temperature and opens up new directions for the future development of highly wear-resistant metallic materials, with significant potential value especially in aerospace and other applications requiring high-performance components.
