As the major strengthening phase, T 1 precipitates contribute over 60% of strength to the
advanced Al-Cu-Li alloys. Its nucleation is the first critical step in determining how many …

Multiple nano-phases and nano-complexes feature the typical microstructures of current
commercial Al-Li alloys. We present a combined first-principles and scanning transmission …

The trade-off of stiffness and ductility of metals has long plagued materials scientists. To
address this issue, atomic structure designs of short-range ordering (SRO) to sub-nanometer …

As a common phenomenon in multiphase systems, interfacial deformation has a significant
impact on the mechanical properties of materials. By utilizing the brittle cleavage and plastic …

For decades, it has been widely accepted that adding Mg to Al alloys decays Young's
modulus of Al alloys. However, the fundamental mechanism for Young's modulus reduction …

U3Si2 is regarded as a promising accident tolerant fuel (ATF) to replace the commercial fuel
UO2; however, grain boundary (GB) embrittlement of U3Si2 caused by irradiation-induced …

Sr has been widely used to convert the faceted needle-like eutectic Si to fibrous Si particles
for producing automotive engines, pistons, and wheels made of Al–Si–Cu alloys. However …

This study explored the structural stability, elastic properties, structural transformation, and
critical concentration of Ni3Al and Ni3M (M= Ti, Ta, Nb) using L12, D024, and DO22 …

Here, we report an extensive screening of homoatomic solute-solute binding energies and
calculate the resulting elastic moduli in aluminum using density functional theory. Following …

This study systematically investigates the energy and electronic properties of Si-segregated
θ′(Al2Cu)/Al semi-coherent and coherent interface systems in Al-Cu alloys using ab initio …
