Variations in solute element distribution occurring in a commercial 2024 aluminium alloy during isothermal ageing treatments at 170 °C for up to 120 h have been characterized using atom probe tomography.An early (0.5 h at 170 °C) rapid increase in hardness was correlated with the formation of fine scale (average 24 atom) solute clusters, comprising principally Mg and Cu, but with minor

The effect of single addition of La or Sm on the microstructures and mechanical properties of an Al-Cu-Mn alloy were investigated by microstructure characterization and tensile test. The results show that addition of La or Sm into the Al-Cu-Mn alloy can remarkably increase the density of θ′ phase and refine the microstructure, and thus, improves the mechanical properties at room temperature

The objectives of this study were to produce ultrafine-grained (UFG) AA2024 aluminum alloy by cryorolling followed by aging and to evaluate its corrosion behavior. Solutionized samples were cryorolled to 85% reduction in thickness. Subsequent aging resulted in a UFG structure with finer precipitates of Al 2 CuMg in the cryorolled

Abstract Understanding the composition evolution of grain boundaries and grain boundary precipitation at near-atomic scale in aluminum alloys is crucial to tailor mechanical properties and to increase resistance to corrosion and stress corrosion cracking. Here, we elucidate the sequence of precipitation on grain boundaries in comparison to the bulk in a model Al-Zn-Mg-Cu alloy. We investigate

In these alloys, the phase formed by combination of the excess soluble elements with the aluminum will never be dissolved, although the shapes of the undissolved par- ticles may be changed by partial solution. Most of the heat-treatable aluminum alloy systems exhibit multistage precipitation and undergo accompanying strength
