Abstract

In contrast to conventional alloys, multicomponent high-entropy alloys (HEAs) have emerged as promising candidates in the field of advanced materials because of their unique composition, microstructure, mechanical and thermal properties, rendering these materials well-suited for a diverse range of applications. For high temperature applications, understanding the hot workability of HEAs is essential for optimizing their processing conditions, tailoring their microstructures and mechanical properties. The current review provides a comprehensive overview of the hot workability of HEAs, including the compression phenomenon observed during hot deformation, the application and use of processing maps, modeling approaches for predicting flow stress, and the deformation mechanisms involved. Different design strategies applicable to HEAs for high-temperature applications have been discussed in this review. The prediction of hot deformation behaviors and processing maps of different HEAs can benefit the research community in designing and developing HEAs for high-temperature applications. Furthermore, we highlight the future scope and challenges in this field.

高温高熵合金热变形行为研究综述

与传统合金相比，多组分高熵合金（HEAs）由于其独特的成分、微观结构、机械和热性能，在先进材料领域成为有希望的候选者，使这些材料非常适合各种应用。对于高温应用，了解HEAs的热加工性对于优化其加工条件，定制其显微结构和机械性能至关重要。本文综述了HEAs的热可加工性，包括热变形过程中观察到的压缩现象、加工图的应用和使用、预测流动应力的建模方法以及所涉及的变形机制。本文讨论了适用于高温应用的HEAs的不同设计策略。不同HEAs的热变形行为预测和加工图可以为设计和开发高温应用HEAs提供参考。此外，我们强调了该领域未来的范围和挑战。图形抽象

期刊介绍： Metals and Materials International publishes original papers and occasional critical reviews on all aspects of research and technology in materials engineering: physical metallurgy, materials science, and processing of metals and other materials. Emphasis is placed on those aspects of the science of materials that are concerned with the relationships among the processing, structure and properties (mechanical, chemical, electrical, electrochemical, magnetic and optical) of materials. Aspects of processing include the melting, casting, and fabrication with the thermodynamics, kinetics and modeling.
