Nanoindentation near the edge. Journal of Materials Research 2009, 24 (3), 1016-1031.Jakes JE, Frihart CR, Beecher JF, Moon RJ, Resto PJ, Melgarejo ZH, Sua´rez OM, Baumgart H, Elmustafa AA, Stone DS (2009) Nanoindentation near the edge. J Mater Res 24(3):1016-1031...
To address this issue, nanoindentation mapping was performed near the edge of cubic samples made from high-speed steel composed of a soft metal matrix and hard primary carbides. The high-speed steels' heat treatment was varied to achieve two microstructurally distinctive material states featuring: I...
It is worth noting that nanoindentation hardness of brittle ceramics is, in general, determined primarily by the dynamic crack extension resistance in the near surface bulk material, and therefore should be more relevant to fracture toughness than to plastic deformation resistance. However, surface ...
Piuma is a compact, standalone, and manual nanoindentor enabling the exploration of mechanical properties from micro- to macro scales in near physiological conditions. Discover more Chiaro Chiaro is a microscope-compatible, manual nanoindentation system that allows you to combine unique mechanical insight...
If, on the contrary, the imprint is small compared to the size of the individual particles, and is near the centre of a particle (or matrix) and sufficiently far from the interface with another phase, the property of the phase alone is obtained. However, reliable indenter positioning is ...
Single crystals of gamma-TiAl cannot be grown in the near-stoichiometric compositions that are present inside two-phase gamma-alpha2-microstructures with attractive mechanical properties. Therefore, the single-crystal constitutive behavior of gamma-TiAl was studied by nanoindentation experiments in single-...
After indenter retraction, however, the twins under the indenter re-adjust to the surrounding lattice and only the near-surface twins in the pile-up survive. The importance of detwinning in Ta after stress release has already been demonstrated in previous studies30,31....

The nanoindentation was carried out at a constant indentation strain rate and indents were separated from each other by at least 50 μm. Here, a total of 5 nanoindentation experiments at different positions were carried out. The FIB cutting position is chosen near the indenter tip, and cutting...
For single crystalline NPs under compression along 0001 at RT, dislocation nucleation initiated from the contact area (between the indent and NPs) within the rhombohedral slip system whereas bicrystals demonstrated reorganization of atoms near the contact between the indent and the grain boundary prior...
