| Abstract Scope |
Over the past 4 decades, nanoindentation technique has been widely used to estimate the various mechanical properties of the small volume in a material at much smaller loads and size scales than conventional (micro-)hardness tests. Now, the technique is being considered not only as a commonplace tool for characterizing hardness and modulus at surfaces (following the standards based on the Oliver-Pharr method) but as an important technique for better understanding of the underlying mechanisms of small-scale mechanical/physical behavior from materials science viewpoints. In this presentation, some recent applications of nanoindentation technique in the research of advanced structural materials such as high-/medium-entropy alloys and additively manufactured alloys will be briefly introduced. Especially, the works on high-pressure torsion (HPT) processed bulk nanocrystalline or ultrafine-grained alloys (whose development was largely contributed by Prof. Langdon) will be a good example to show how this ~40-years-old technique is still playing a crucial role in novel structural materials R&D. |
