Bibliometric analysis of machining of titanium alloy research

Abstract

Abstract This paper aims to acquaint the readers about the research trends in machining of titanium alloy related literature based on the data collected from Web of Science (WoS) databases using bibliometric analysis. A total of 1291 results were obtained from WoS database. The results were analyzed based on aspects like distribution of the obtained research documents based on language, type, subject areas covered, total publications of authors, and citation counts of authors over the years in WoS database. Most of the publications are either in the engineering and material science domain. Further, lists of most productive authors, institutions, countries (along with geographical representation) are presented. China is the leading country in this research field but the Nanjing University of Aeronautics and Astronautics of China have the highest number of publications among all other institutes around the world. The author's keywords co-occurrence analysis network is visualized using VOS viewer. The study shows that ‘Minimum quantity lubrication (MQL)’, ‘nanofluid’, ‘cryogenic machining’, ‘cutting temperature’, ‘CFD’, ‘microstructure’, ‘sustainable machining’, ‘green machining’, ‘tool wear’, ‘micromachining’, ‘optimization parameters’, ‘tool life’ with major machining process like turning, milling, grinding, drilling, EDM and WEDM, etc. are the most recent keywords that indicate the hot topics and future research directions in the machining of titanium alloy field. This study also shows that the annual growth rate in machining of titanium alloy research is 16.94%, which indicates that machining of titanium alloy research has gained rapid attention since 2016 and gradually evolved over the years. By referring to this paper, researchers will be able to make calculated decisions and will get useful information for future research directions.
