Residual stress is one of the main factors affecting the mechanical properties of materials,
such as their strength, plasticity and surface integrity. For instance, tensile stress conditions …

Different approaches to the preparation of superhard coatings such as intrinsically
superhard materials, coatings whose hardness is enhanced by energetic ion bombardment …

High-power flip-chip light-emitting diodes (FCLEDs) suffer from low efficiencies because of
poor p-type reflective ohmic contact and severe current crowding. Here, we show that it is …

A comprehensive computational study was undertaken to identify the extent to which elasto-
plastic properties of ductile materials could be determined from instrumented sharp …

Ultra-low load indentation, also known as nanoindentation, is a widely used tool for
measuring the mechanical properties of thin films and small volumes of material. One of the …

Finite element simulation of conical indentation of a wide variety of elastic-plastic materials
has been used to investigate the influences of pileup on the accuracy with which hardness …

A general methodology is proposed for the determination of surface residual stresses and
residual plastic strains using instrumented sharp indentation. The residual stresses and the …

The influence of applied stress on the measurement of hardness and elastic modulus using
nanoindentation methods has been experimentally investigated using special specimens of …

In this paper, a review of the present status of the research and technological development
in the field of superhard nanocomposite coatings is attempted. Various deposition …

As the size of electronic and mechanical devices shrinks to the nanometre regime,
performance begins to be dominated by surface forces. For example, friction, wear and …
