The current status of ion beam processing of GaN is reviewed. In particular, we discuss the
following aspects of ion implantation into GaN:(i) damage build-up and amorphization,(ii) …

A methodology is developed which extends the combinatorial approaches to structural
materials research and development. This high-efficiency methodology employs diffusion …

Inconel 718 is a material under consideration for areas in the target region of the spallation
neutron source (SNS), now under construction at Oak Ridge National Laboratory (ORNL) in …

Plastic zone evolution in Al–2 wt% Si metal films on silicon and sapphire substrates was
studied using nanoindentation and atomic force microscopy (AFM). AFM was used to …

A new analysis technique for calculating the hardness, modulus, and contact area from
indentation data obtained using pyramidal or conical indenters was formulated and …

We report the results of several experiments isolating the effect of long-range order on
mechanical properties of intermetallic compounds. Kinetically disordered FCC Ni3Al (Ni …

Nanoindentation, nanoscratch and ball-on-disk tests were used to determine the film
thickness effect on the mechanical and tribological properties of nitrogenated diamond-like …

The use of tribological coatings with film thicknesses in the submicrometer regime is an
increasing field of applications. In this work diamond-like carbon films with a thickness of …

We have investigated the effect of chamber pressure and atmosphere on the microstructure
and nanomechanical properties of amorphous carbon thin films prepared by pulsed laser …

An optimization system, which combines a particular boundary element method and a
modified Levenberg–Marqardt method, and which can be used to determine material …
