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.

为明确长江中游南部地区影响油菜产量的关键气象因子,提高油菜育种效率,本文以长江中游2018-2020三年试验点的气象数据及参加国家冬油菜品种试验的106个油菜品种为基础数据进行分析。结果表明:相同油菜品种栽培条件下,南部地区的单产为2307.15 kg/hm^(2),比北部偏低25.28%,其中千粒重、每角粒数、有效分枝数和菌核病病情指数差异最大,分别降低16.09%、4.43%、9.19%和27.84%。通径分析表明南部地区油菜品种产量构成与北部显著不同,南部地区对小区产量直接作用大小依次为有效分枝数(0.2538)>千粒重(0.2887)>每角粒数(0.1469)>菌核病病情指数(-0.3981),北部地区对小区产量直接作用大小依次为全生育期(0.5798)>单株有效角果数(0.2128)>每角粒数(0.1624)>千粒重(-0.1630)。气象因子与产量回归分析表明,南部地区油菜产量与11月平均温度显著负相关,1月和3月昼夜温差显著正相关,11月和12月最低温显著负相关,2月和4月最低温极显著正相关,2月和4月降雨量显著负相关。从整个生育期看,长江中游南部地区主要影响油菜产量气象因子为昼夜温差、最低温度和降雨量。育种策略中,南部地区除了选育耐高温性和耐渍涝的油菜品种外,还应加强对千粒重、有效分枝数、每角粒数的选择,为进一步提高南部地区油菜单产提供理论依据。

为了探究激光冲击强化对Ti-6Al-4V合金榫齿结构高低周复合疲劳行为的影响,本文对经过激光冲击强化处理的Ti-6Al-4V榫齿结构的表面完整性特征和高低周复合疲劳性能进行测试。结果表明:相比于未经过激光冲击强化处理的原始榫齿结构,激光冲击榫齿结构的高低周复合疲劳寿命提高729%。激光冲击改变了榫齿结构接触区域的微动磨损特征。原始榫齿结构表现为大尺寸的脱层磨损坑,坑底部诱发微裂纹并向基体内扩展,而激光冲击榫齿结构表现为小尺寸脱层薄片。此外,激光冲击还降低榫齿结构的疲劳裂纹扩展速率。激光冲击强化抗高低周复合疲劳作用显著,这主要归因于激光冲击强化层改变疲劳裂纹萌生方式,并抑制裂纹早期扩展。
