Abstract The indentation response of aluminum–matrix SiC particle-reinforced metal matrix composites (PR-MMCs) impressed by a circular indenter has been numerically analyzed under the two-dimensional discrete dislocation plasticity combined with the ANSYS® finite element software.

Nano-indentation analysis was employed to investigate the mechanical response of heavy ion irradiated X-750 Ni-based superalloy in both solution-treated (ST) and precipitation-hardened (PH) conditions. Helium pre-implantation was carried out at 300 °C up

In this work, the cross-sectional nano-indentation of ion-irradiated steels is simulated by the crystal plasticity finite element method. Two dominant features, including the non-uniform irradiation hardening and indentation size effect, are ...

Determination of yield stress from nano-indentation experiments
European Journal of Mechanics - A/Solids, 2015Abstract The aim of this paper is to investigate the possibilities of getting information on the initial yield stress Y from nano-indentation experiments with sharp indenters. Berkovich indenters have been used for the experiments and the data evaluation was performed by using two expanding cavity models (ECM) described in the literature, one for ...

Nano-indentation of scratched poly(methyl methacrylate) surfaces
Tribology Letters, 2005The paper describes an experimental study of the nano-indentation hardness profiling of scratches, of various depths, produced upon the surface of a poly(methyl methacrylate). The method has limited spatial resolution and typically the indent size, and hence the volume of deformed material sensed, was in the worst cases one-tenth of the scratch width ...

One of the problems limiting the application of Stellite 6 coating is the residual stress resulting in cracks in the coating easily. In order to reduce the residual stress and increase the nano-indentation hardness, La2O3 was added to Stellite 6 coating ...
