In order to develop high-strength Al-Cu-Mg-Ag alloys used in the aerospace, this paper
studied the mechanical properties and microstructure of Al-Cu-Mg-Ag alloys with T6I4 …

Abstract Effect of deep cryogenic treatment (DCT) on the aging behavior and tensile
properties of Al–Cu–Mg–Ag alloy was investigated. Results show that DCT of Al–Cu–Mg–Ag …

The T 1 phase is the highest density and most prominent strengthening effect precipitate in
Al–Cu–Li alloys, and it undergoes a complex dynamic evolution during hot deformation …

The coarsening behavior of strengthening particles has been studied in a peak-aged Al–Cu–
Mg–Ag alloy during creep at 150° C and 165° C. The average {111} Al Ω plate thickness and …

In the quest for excellent light-structural materials that can withstand mechanical extremes
for advanced applications, design and control of microstructures beyond current material …

The formation energies of the structures of Ω′ and T 1 precipitates having different
interfacial compositions are calculated by density functional theory. Our results show that the …

In this work, the effect of laser shock peening (LSP) on the microstructure evolution and
deformation mechanism of a lubricated brass surface layer has been systematically …

Abstract Ω, T 1, Y, η'and η nano-phases in different series Al alloys are known to all
precipitate along the major slip planes {111} Al. Their precipitation in multi-element cross …

T 1 precipitate plates of one, two and three unit-cell thicknesses in a peak-aged Al-Cu-Li-Mg-
Ag alloy are examined using atomic-resolution high-angle annular dark-field (HAADF) …

The interaction mechanism between the precipitates and moving dislocations is one of the
key factors that governs the mechanical properties of precipitation-hardened aluminum …
