Nanoscratching meets nanoindentation
Zeitschrift für Kristallographie - Crystalline Materials, 2016AbstractA specimen of high-carbon nitrogen-doped steel has been synthesized to supplement previous studies on wootz-like steels. A comparison of different states of material as well as one of distinct methods of hardness testing has been performed. Electron microscopy of the specimens’ microstructure revealed nano-structuring similar to that observed ...

Nanoindentation of dental composites
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005AbstractThe intent of this project was to evaluate the elastic modulus and hardness of four composites with different fillers, a microfill, a hybrid, a dental resin cement, and a fiber filler, using nanoindentation. An indentation load of 0.001 N was used and 100 indents per specimen were taken. The elastic modulus measured for the Choice composite was

Time-Dependent Nanoindentation
2004In 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.

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 (

Small-scale polymers are increasingly being applied to a variety of fields, making it important to understand the behavior of polymers at small length scales. Indentation size effects (ISE) is the apparent increase in material-specific properties at very low indentation depths.

Nanoindentation Test Instruments
2002Interest in nanoindentation has spawned a number of nanoindentation instruments that compete on a world market. Purchasers of such instruments are universities, private and government research organisations, and quality control laboratories. There is particular interest within the semiconductor industry that is concerned with the mechanical properties ...

Applications of Nanoindentation
2004Nanoindentation 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.

Nanoindentation Test Standards
2002The ISO (the International Organization for Standardization) has recently issued a draft international standard ISO 14577 entitled “Metallic materials—Instrumented indentation test for hardness and materials parameters [1].” This draft standard covers depth-sensing indentation testing for indentations in the macro, micro and nano depth ranges and also ...
