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.
