Nanoindentation of coatings

Journal of Physics D: Applied Physics, 2005
A range of mechanical properties of a coating/substrate system may be obtained using indentation tests, and with the emergence of continuously recording indentation testing with nanometre penetration (often called nanoindentation) the mechanical properties of very thin coatings (

Hydrogen embrittlement of tungsten induced by deuterium plasma: Insights from nanoindentation tests

Journal of Materials Research, 2018
Hydrogen exposure has been found to result in metal embrittlement. In this work, we use nanoindentation to study the mechanical properties of polycrystalline tungsten subjected to deuterium plasma exposure.

Nanoindentation of natural diamond

Philosophical Magazine A, 2002
Abstract This study demonstrates that the plane-strain Young's moduli E* = E/(1 - v 2) of natural diamonds with a weight of less than 0.2 carat can be determined by the technique of nanoindentation, where E is Young's modulus and v is Poisson's ratio. The indentation test with a Berkovich indenter was conducted at loads of 50, 100 and 300 mN for three ...

Applications of Nanoindentation

2004
Nanoindentation finds a wide application. The test results provide information on the elastic modulus, hardness, strain-hardening, cracking, phase transformations, creep, fracture toughness, and energy absorption. Since the scale of deformation is very small, the technique is applicable to thin surface films and surface modified layers.

Investigation on surface/subsurface deformation mechanism and mechanical properties of GGG single crystal induced by nanoindentation.

Applied Optics, 2018
In this paper, nanoindentation tests of GGG single crystal are performed on an Agilent G200 nanoindenter. The surface morphology and subsurface deformation mechanism induced by the nanoindentation are analyzed by a scanning electron microscope and a ...

Nanoindentation hardness of a Steigmann–Ogden surface bounding an elastic half-space

Mathematics and mechanics of solids, 2018
Previous studies demonstrate that, for nanostructures under transverse bending, the effective Young modulus is appreciably greater (in magnitude) than that of the same elements under axial loads.

Time-Dependent Nanoindentation

2004
In general, materials can resist deformation in a solid-like or viscous-like manner. Solid-like materials store energy under deformation, and upon removal of stress, returns to its original state. Viscous materials dissipate energy during deformation and upon removal of stress, remains in its deformed state.

Other Techniques in Nanoindentation [PDF]

, 2004
Nanoindentation has proven to be a very versatile method of mechanical testing. It is often considered to be non-destructive in the sense that the indentations are in general, too small to be visible to the naked eye and, for the most part, the test does not impair the structural integrity of the specimen. Compared to the previous chapters, we now turn
