Comparative simulation study of the structure of the plastic zone produced by nanoindentation
(Pergamon-Elsevier Science Ltd, 2015-11)
Using molecular-dynamics simulation, we study nanoindentation in fcc (Cu and Al) and bcc (Fe and Ta) metals by a spherical indenter and investigate the size of the plastic zone generated. We find that while it does not ...
Mechanical characterization of nano-reinforced silica based sol-gel hybrid coatings on AISI 316L stainless steel using nanoindentation techniques
(Elsevier Science Sa, 2009-07)
One way to enhance the surface properties of metals used as surgical implants such as wear or protective behaviour is to use hybrid organic-inorganic sol-gel coatings. The addition of SiO2 colloidal particles to some hybrid ...
Nanoindentation tests of heavy-ion-irradiated Au foams - Molecular dynamics simulation
(American Institute of Physics, 2018-06)
Irradiation by light ions may change the mechanical properties of nanofoams. Using molecular-dynamics simulation, we study the effect of irradiating a Au foam (porosity, 50%, and ligament diameter, 3 nm) with heavy ions: ...
Influence of pile-up on nanoindentation measurements in Cu–2wt.%Be samples with precipitates
(Elsevier Science, 2019-11)
The influence of pile-up on the nanoindentation measurements in Cu–2wt.%Be samples with precipitates was carefully studied. The precipitates were formed by aging treatments for 1 h at different temperatures between 540 and ...
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
(Elsevier Science, 2020-06)
Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ...
Improved interfacial transition zone between aggregate-cementitious matrix by addition sugarcane industrial ash
(2017-07-01)
The aim of this study was to evaluate the influence of sugarcane industrial ash (SCIA) on mechanical properties of interfacial transition zone (ITZ) between aggregates and cementitious matrix by nanoindentation technical ...
