Nano and Micro indentation studies of bulk zirconia and EB PVD TBCs [PDF]
In order to model the erosion of a material it is necessary to know the material properties of both the impacting particles as well as the target. In the case of electron beam (EB) physical vapour deposited(PVD) thermal barrier coatings (TBCs) the ...

Conventional Vickers and true instrumented indentation hardness determined by instrumented indentation tests [PDF]
We evaluate Vickers hardness and true instrumented indentation test (IIT) hardness of 24 metals over a wide range of mechanical properties using just IIT parameters by taking into account the real contact morphology beneath the Vickers indenter ...

Analysis of indentation size effect in copper and its alloys [PDF]
For describing the indentation size effect (ISE), numerous models, which relate the load or hardness to the indent dimensions, have been proposed. Unfortunately, it is still difficult to associate the different parameters involved in such relationships ...

The contribution of 211 particles to the mechanical reinforcement mechanism of 123 superconducting single domains [PDF]
Hardness and fracture toughness of Dy-123 single-domains were studied by Vickers micro-indentation. A significant anisotropy of the mechanical properties was observed. Hardness tests give higher values when performed in (001) planes rather than in planes

Exfoliated Graphite Reinforced PMMA Composite: A Study on Nanoindentation and Scratch Behavior
The present work aims to compare the scratch hardness (Hs) with the indentation hardness (HIT) obtained from nanoindentation measurements of exfoliated graphite/poly (methyl methacrylate) (EG/PMMA) composites. EG/PMMA composites with thickness 50 μm each

Mechanical properties of Al2O3 inverse opals by means of nanoindentation [PDF]
In order to understand the mechanical behaviour of Al2O3 inverse opals, nanoindentation techniques have been implemented in material layers with three different microstructures, in terms of hollow or polystyrene spheres, with Al2O3 shells of distinct ...
