Design of stable nanocrystalline alloys.
TL;DR: In this paper, a theoretical framework with which stable nanostructured tungsten alloys can be designed is developed, and a nanostructure stability map based on a thermodynamic model is applied to design stable nan-structure alloys.
Design of Stable Nanocrystalline Alloys
TL;DR: A theoretical framework to create stability maps to identify potential alloys with the greatest thermal stability is developed and a candidate alloy, W-Ti, is identified and demonstrated substantially enhanced stability for the high-temperature, long-duration conditions amenable to powder-route production of bulk nanostructured tungsten.

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.
