Bibliometric Analysis and Visualization of Nanoindentation Research.

Nanoindentation has gained significant attention as a method for the quantitative characterization of mechanical properties of materials at micro- and nanoscales. This study investigates trends in nanoindentation technology by visualizing and analyzing relevant publications. To achieve this, CiteSpace was utilized to analyze 14 373 papers from the Web of Science core database published between 2013 and 2022. The analysis examined the status and trends in nanoindentation technology, focusing on the publication counts, contributing countries, institutions, authors, and keywords. The results indicate a growing number of publications related to nanoindentation technology globally, with China leading in publication output. Upadrasta Ramamurty is recognized as the most prolific author, while the work of W.C. Oliver and G.M. Pharr has received substantial citations. Six research hotspots and their associated content are identified as current frontiers in this field. Future investigations may concentrate on the applicability range, measurement accuracy, and theoretical modeling of this technique. This review aims to assist scholars interested in nanoindentation technology in quickly identifying research priorities from a new perspective and anticipating the future trajectory of this field.
