Positron is the only probe that can detect individual atomic vacancies and small and large
vacancy clusters induced by irradiation with remarkable sensitivity, providing information …

Positron is an excellent probe of lattice defects in solids. A thermallized positron delocalized
in lattice can be trapped at open volume defects, eg vacancies, dislocations, grain …

High strength aluminum alloys are widely used but their strength is reduced as nano-
precipitates coarsen rapidly in medium and high temperatures, which greatly limits their …

Abstract In third-generation Al–Cu–Li alloys, T 1, S', and θ'precipitates are the primary
strengthening phases, and the strength-ductility synergy of the alloys depends strongly on …

We present an extensive first-principles database of solute-vacancy, homoatomic,
heteroatomic solute-solute, and solute-solute-vacancy binding energies of relevant alloying …

The 2024 aluminum alloy has excellent mechanical and low corrosion due to the existence
of the high Cu levels, which shortens its service life. In this paper, we have systematically …

Abstract For Al–Cu–Mg–Ag alloys, Ω phases play a crucial role in determining the
mechanical property at room and elevated temperatures. In this work, an Al–5.5 wt.% Cu …

This article begins with pure aluminum and a discussion of the form of the crystal structure
and different unit cells that can be used to describe it. Measurements of the face-centered …

This encyclopedia, written by authoritative experts under the guidance of an international
panel of key researchers from academia, national laboratories, and industry, is a …

Abstract Effect of minor Sn additions (0.05, 0.10 wt%) on the microstructure and room-
temperature mechanical properties of Al-3.0 wt% Cu alloy was studied by using …
