TLDR
In this article, the authors report on the observation of real-time-resolved room temperature grain growth in nanocrystalline metals and find that neither the time evolution of size can be modeled by standard growth theories nor are there any other systems aware to us that manifest a similar growth behaviour.About:

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.
Journal ArticleDOI
Defect-interface interactions
TL;DR: In this paper, the authors review the present understanding of defect-interface interactions in single-phase and two-phase metal and oxide nanocomposites, emphasizing how interface structure affects interactions with point, line, and planar defects.

TL;DR: A novel interface engineering strategy is proposed to simultaneously achieve superior irradiation tolerance, high strength, and high thermal stability in bulk nanolayered composites of a model face- centered-cubic (Cu)/body-centered-cUBic (Nb) system.

TL;DR: This discovery proves that interfaces can be designed within bulk nanostructured composites to radically outperform previously prepared bulk nanocrystalline materials, with respect to both mechanical and thermal stability.

TL;DR: In this paper, the authors discuss the extent to which we are able to formulate quantitative, physically-based models which can be applied to metal-forming processes, and the subjects treated in this book are all active research areas and form a major part of at least four regular international conference series.
