Dislocation-mediated Mechanisms of Mass Transport around Nanoindentations in Fcc Metals [PDF]
, 2002 We present evidence for the operation on reconstructed Au(001) of a novel mechanism, involving dislocation motion, which is much more efficient than surface diffusion to redistribute mass around nanoindentations.

Stress-Induced Phase Transformations of Micro-Crystalline Silicon Films Arising at Nanoindentations [PDF]
, 2011 The stresses and strain values at various indentation depths are applied to determine the Gibbs free energy at various phases. The intersections of the Gibbs free energy lines are used to determine the possible paths of phase transitions arising at ...

Nanoindentation of surfactant aggregates
Journal of Colloid and Interface Science, 2010 Surfactants are important for a wide range of applications dealing with one-dimensional nanoscale materials, including dispersion of carbon nanotubes, as organic templates in mesoporous silica thin films, and for the fabrication of silica nanowires. There is therefore great interest in better understanding the structure and properties of surfactant ...

Dislocation Reaction Mechanism for Enhanced Strain Hardening in Crystal Nano-Indentations
Crystals, 2019 Stress−strain calculations are presented for nano-indentations made in: (1) an ammonium perchlorate (AP), NH4ClO4, {210} crystal surface; (2) an α-iron (111) crystal surface; (3) a simulated test on an α-iron (100) crystal surface.
