Owing to their exceptional properties, high-entropy alloys(HEAs) and high-entropy materials have emerged as promising research areas and shown diverse applications. Here,the recent advances in the field are comprehensively reviewed,organized into five sections. The first section introduces the background of HEAs, covering their definition, significance,application prospects, basic properties, design principles, and microstructure. The subsequent section focuses on cutting-edge high-entropy structural materials, highlighting developments such as nanostructured alloys, grain boundary engineering,eutectic systems, cryogenic alloys, thin films, micro-nano-lattice structures, additive manufacturing, high entropy metallic glasses, nano-precipitate strengthened alloys, composition modulation, alloy fibers, and refractory systems. In the following section, the emphasis shifts to functional materials, exploring HEAs as catalysts, magneto-caloric materials, corrosion-resistant alloys, radiation-resistant alloys, hydrogen storage systems, and materials for biomedicine. Additionally, the review encompasses functional high-entropy materials outside the realm of alloys, including thermoelectric, quantum dots, nanooxide catalysts, energy storage materials, negative thermal expansion ceramics,and high-entropy wave absorption materials. The paper concludes with an outlook, discussing future directions and potential growth areas in the field. Through this comprehensive review,researchers, engineers, and scientists may gain valuable insights into the recent progress and opportunities for further exploration in the exciting domains of high-entropy alloys and functional materials.

为增强板片蒸发式冷凝器板外侧气液两相流动以提升传热能效,用数值模拟分析了顺流与逆流下水膜流动形态,并通过改变淋水量、风速、板间距等主要影响因素,得出了2种流态下的复合传热系数与板间压损。从控制参数范围内的实验结果结合数值模拟分析可知:当风速一定,顺流与逆流下复合传热系数都随淋水量增加先增后减,最佳淋水量都在0.1111 kg/s,且淋水量对板间压损影响极小;当淋水量一定,顺流复合传热系数随风速的增幅呈小-大-小的非线性状,最佳风速在3 m/s,逆流复合传热系数的增幅呈先正后负,最佳风速在2.5 m/s,且2种流态下的板间压损都随着风速增加而增加;随着板间距增加,复合传热系数及板间压降都随之减小。
