About this Research Topic
Nanoindentation has become an ubiquitous method to characterize the mechanical properties of materials at the nanoscale for applications such as thin film coatings and micromechanical devices, for which bulk tests are difficult or impossible to make. Mechanical properties (i.e. hardness and Young’s modulus, etc.) are of critical importance when designing and fabricating the practical devices concerned. Thus, understanding the mechanical properties of materials has been of great interest for fabricating efficient and endurable devices. With high-resolution load-displacement data, discrete events including dislocation source activation, shear instability initiation, and phase transformations can be detected using a nanoindentation test.
The aim of this Research Topic is to provide recent advances in the preparation and characterization of materials with emphasis on their mechanical properties studied by nanoindentation technique. Of particular interest is the study of nanoindentation of materials that were fabricated by advance (additive) manufacturing, since it is known that they are not behaving the same as conventional bulk machined materials, but find more and more ways into applications, so their nanomechanical properties are important to understand. We welcome all the submission of original research papers, reviews, mini-reviews, and perspectives that introduce a better understanding of emerging materials along with their functional and mechanical properties.
Topics addressed in this Research Topic may include, but are not limited to:
• Preparation and characterization of materials and such as thermoelectrics, topological insulators, metal oxides, multiferroics, metals, and semiconductors, as well as their mechanical properties studied by nanoindentation technique.
• Nanoindentation of materials fabricated by advance (additive) manufacturing
• Modeling of mechanical properties and deformation behaviors of materials.
