Research attention in powder metallurgy (PM) processing of high-entropy alloys (HEAs) is rising. Some reviews have been published but a detailed historical analysis to identify the thematic research areas and prospective future research areas is lacking. Therefore, this study presents a bibliometric literature analysis of PM-processed HEAs by mapping and clustering 700 articles published between 2007 and August 2022 in the Scopus database. The most prolific authors, their collaborators, institutions, and most preferred journals publishing PM-HEA works are identified and mapped. Publication trend shows that significant research attention in the PM processing of HEAs began to gain traction in 2016. The top three journals in this field are Journal of Alloys and Compounds, Materials Science and Engineering A, and Intermetallics. However, co-authorship network analysis does not reveal significant inter-institutional research collaboration indicating that strengthening this area could help to accelerate scientific discovery, enhance technology transfer, and commercialization of HEA products. Based on the co-occurrence frequencies of author keywords, popular research directions are identified, and a systematic review of emerging functional applications is undertaken. This work provides a comprehensive visual reference guide for researchers to deepen their knowledge of this field and delivers insight into prospective future research opportunities to stimulate further ground-breaking works.

高熵合金粉末冶金加工：文献计量分析与系统评价

高熵合金 (HEA) 粉末冶金 (PM) 加工的研究关注度不断上升。一些评论已经发表，但缺乏详细的历史分析来确定主题研究领域和未来的前瞻性研究领域。因此，本研究通过映射和聚类 Scopus 数据库中 2007 年至 2022 年 8 月期间发表的 700 篇文章，对 PM 处理的 HEA 进行了文献计量文献分析。确定并绘制了最多产的作者、他们的合作者、机构以及出版 PM-HEA 作品的最受欢迎的期刊。发表趋势表明，2016 年 HEA 粉末冶金加工领域的研究开始受到关注。该领域排名前三的期刊是合金与化合物杂志、材料科学与工程A、金属间化合物。然而，共同作者网络分析并未揭示重大的机构间研究合作，表明加强这一领域可能有助于加速科学发现、加强技术转让和 HEA 产品的商业化。根据作者关键词的共现频率，确定热门研究方向，并对新兴功能应用进行系统回顾。这项工作为研究人员提供了全面的视觉参考指南，以加深他们对该领域的了解，并深入了解未来的研究机会，以激发进一步的突破性工作。
