An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments
Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this paper, the authors used a Berkovich indenter to determine hardness and elastic modulus from indentation load-displacement data, and showed that the curve of the curve is not linear, even in the initial stages of the unloading process.

Contact and Rubbing of Flat Surfaces
TL;DR: In this article, the authors compared the deduced dependence of the experimental observables on the load with the experimental evidence and concluded that the most realistic model is one in which increasing the load increases both the number and size of the contact areas.

Electrochemical Polarization I . A Theoretical Analysis of the Shape of Polarization Curves
Milton Stern,A. L. Geary +1 more
TL;DR: In this paper, a linear dependence of potential on applied current is described for a corroding electrode by treating it in a manner analogous to that for a non-corroding electrode, and an equation is derived relating the slope of this linear region to the corrosion rate and Tafel slopes.

High tensile ductility in a nanostructured metal.
TL;DR: A thermomechanical treatment of Cu is described that results in a bimodal grain size distribution, with micrometre-sized grains embedded inside a matrix of nanocrystalline and ultrafine (<300 nm) grains, which impart high strength, as expected from an extrapolation of the Hall–Petch relationship.
