Bin's paper "Controlling Interface Structure in Nanoglasses Produced through Hydrostatic Compression of Amorphous Nanoparticles" published in Physical Review Materials.
March 2019
In this study, we expand on the core-shell and columnar nanoglass frameworks to produce a scalable nanoglass model through hydrostatic compression of amorphous nanoparticles stacked in close-packed configurations. A computational method based on the correlation between dilatation and atomic volume distributions during consolidation is also developed to distinguish atoms composing the glass-glass interfacial regions from those located within the amorphous grains.

Wenbo's paper "Grain Boundary Segregation and Intermetallic Precipitation in Coarsening Resistant Nanocrystalline Aluminum Alloys" published in Acta Materialia.
February 2019
In this work, we used a computationally-guided experimental approach to design coarsening resistant nanocrystalline Al-Mg binary alloys. A hybrid Monte Carlo (MC)/molecular dynamics (MD) model was used to explore thermodynamically preferred states in nanocrystalline Al-Mg alloys with a focus on solute distribution and its implications for nanostructure stability.

Streits's paper "In-situ Irradiation Tolerance Investigation of High Strength Ultrafine Tungsten-Titanium Carbide Alloy" published in Acta Materialia.
February 2019
Based on its promising mechanical behavior and improved resistance to recrystallization embrittlement, tungsten alloyed with small amounts of TiC have been investigated as a potential radiation-tolerant material. This study aims to contribute further to the knowledge of these alloys by presenting the findings of in-situ-irradiation on as-HIPed W with 1.1 wt% TiC.
