... containing the aforementioned copolymer differs in the proportion of the epoxy resin resulting in the production of a coating with a gradient from hard to soft from the substrate to the top. Nanomechanical performance is accessed via nanoindentation, providing information for structural and mechanical...

...Dimitrios A. Dragatogiannis; Elias P. Koumoulos; Ioannis A Kartsonakis; Costas A. Charitidis Purpose – The study of nanoindentation as a reliable method to extract creep properties as well as for fundamental understanding of deformation mechanisms at small length scales is an open interesting...

... electron microscopy and X-ray diffraction, respectively. The mechanical integrity of the produced thin films was evaluated through nanoindentation technique. Findings – The obtained results indicate that Co₂B thin film exhibits the highest nanomechanical properties (i.e. H...

...Sp. Pantelakis; Elias P. Koumoulos; Costas A. Charitidis; Nikolaos M. Daniolos; Dimitrios I. Pantelis Purpose The purpose of this paper is to determine if the nanoindentation technique is a reliable method and whether it can be used to measure the surface hardness (H) in friction stir welded...

... of aluminum alloy by nanoindentation technique, through investigation of creep behavior. Additionally, possible explanations on the time dependent behavior and the influence of the hold period at maximum load and the loading rate on the elastic modulus and hardness results are also analyzed and discussed...

...Sp. Pantelakis; Costas A. Charitidis; Dimitrios A. Dragatogiannis Purpose The purpose of this paper is to investigate the use of nanoindentation with a Berkovich indenter as a method of extracting equivalent stress‐strain curves for the base metal and the welded zone of a friction stir welded...
