The mechanism of L12 phase precipitation, microstructure and tensile properties of Al-Mg-Er-Zr alloy
TL;DR: In this article, the effect of Er on precipitation behavior and properties of Al-3Mg-0.25Er-Zr alloy was investigated using hardness measurements and electron microscopy techniques.
Journal ArticleDOI
A first principles investigation on the influence of transition-metal elements on the structural, mechanical, and anisotropic properties of CaM2Al20 intermetallics.
TL;DR: The anisotropy in elasticity, mechanical properties and electronic properties of CaM2Al20 compounds were investigated and the results of elastic modulus, hardness and elastic constants explain that CaM 2Al20 intermetallics have higher hardness and better resistance to deformation change than pure aluminum.
Journal ArticleDOI
First-principles prediction of the physical properties of ThM2Al20 (M= Ti, V, Cr) intermetallics
TL;DR: In this article, the structural stability, elastic properties, ductile or brittle behavior, anisotropy, dynamical stability and thermodynamic properties of pure Al and ThM2Al20 intermetallics were explored.

Gang Sha,Alfred Cerezo +1 more
TL;DR: In this paper, the formation of metastable platelets in early-stage precipitation of a 7050 Al alloy aged at 121 °C was investigated using transmission electron microscopy, together with 3-dimensional atom probe analysis.

Influence of scandium and zirconium on grain stability and superplastic ductilities in ultrafine-grained Al-Mg alloys
Sungwon Lee,A. Utsunomiya,Hiroki Akamatsu,Koji Neishi,Minoru Furukawa,Zenji Horita,Terence G. Langdon +6 more
TL;DR: Experiments were conducted to evaluate the grain refinement introduced by equal-channel angular pressing (ECAP) in three different Al-3% Mg alloys containing either 2% Sc, 2% Zr or a combination of 2%Sc and Zr as mentioned in this paper, but superplasticity was not achieved in the Al-Mg-Zr alloy due to the onset of rapid grain growth at 573 K.

Dispersoid precipitation and process modelling in zirconium containing commercial aluminium alloys
TL;DR: In this paper, a general physical model has been developed for the precipitation of Al3Zr dispersoids in aluminium alloys, which has been used to study the effects of homogenization conditions and alloy composition on dispersoid formation and has been shown to be a powerful tool for optimising the dispersoid distribution in 7xxx series aluminum alloys.
