摘    要:高熵合金目前的研究大多针对块体、粉体、涂层、薄膜等领域,在其他领域的研究较少且缺乏统一分类。本文根据当前高熵合金研究进展,对所有研究的高熵合金种类进行了划分,介绍了元素选取原则,总结了高熵合金制备方法,综述了高熵合金研究机构、研究形式、研究内容等现状,展望了高熵合金应用前景,提出了当前高熵合金机理研究较少、性能研究不全面、热稳定性研究不系统、涂层制备工艺参数有待优化、轻质高熵合金设计、课题研究领域拓展等系列科学问题并给出针对解决方法,对于高熵合金课题未来的应用领域拓展研究方向有一定的指导意义。

关 键 词:高熵合金  分类  制备方法  研究现状  应用前景  科学问题

Progress in Preparation and Research of High Entropy Alloys
Abstract:The current high entropy alloys' studies are most in block,powder,coating,film and other areas.There are few studies of high entropy alloys in other areas and they are lack of unified classification.According to the current high entropy alloys' research situation,The paper has focused on the classification on all kinds of high entropy alloys having been researched,introduced the selecting principle of elements,summarized the preparation methods,reviewed the research institutions,research methods and research contents of high entropy alloys,prospected the application prospect of high entropy alloys,put forward a series of scientific problems of high entropy alloys,including less research on mechanism,incomplete performance research,unsystematic thermal stability study,preparation process parameters to be optimized,lightweight high entropy alloys' design,the expansion on the research field,etc,and the solutions have been given.Those have certain guiding significance for the expansion of the application of high entropy alloys subjects in the future research direction.
Keywords:high entropy alloy  classification  preparation method  research status  application prospect  scientific problem
