Abstract

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.

梯度纳米结构对Ti/AlCoCrFeNi复合材料力学性能的影响

尽管在工程应用中存在挑战，但金属材料的强度、塑性和耐磨性仍然存在，特别是在室温下，这些特性对材料的性能至关重要。然而，在揭示高熵合金（HEA）和细晶粒组织（GNS）对室温性能的影响机理方面，目前的研究还存在一定的空白。本研究的目的是研究室温条件下HEA颗粒与GNS的协同作用及其对钛基复合材料性能的增强作用。实验结果表明，随着GNS的形成和HEA颗粒的强化作用，材料的强度和耐磨性显著提高。该研究为室温下HEA和GNS之间的相互作用提供了新的见解，为未来高耐磨金属材料的发展开辟了新的方向，特别是在航空航天和其他需要高性能组件的应用中具有重要的潜在价值。

期刊介绍： This journal is a platform for publishing innovative research and overviews for advancing our understanding of the structure, property, and functionality of complex metallic alloys, including intermetallics, metallic glasses, and high entropy alloys. The journal reports the science and engineering of metallic materials in the following aspects: Theories and experiments which address the relationship between property and structure in all length scales. Physical modeling and numerical simulations which provide a comprehensive understanding of experimental observations. Stimulated methodologies to characterize the structure and chemistry of materials that correlate the properties. Technological applications resulting from the understanding of property-structure relationship in materials. Novel and cutting-edge results warranting rapid communication. The journal also publishes special issues on selected topics and overviews by invitation only.
