Surface severe plastic deformation induced solute and precipitate redistribution in an Al-Cu-Mg alloy

The precipitate and solute distribution in a surface severely plastically deformed Al-Cu-Mg alloy were revealed by means of transmission electron microscopy and atom probe tomography. Accompanying gradient grain structure, there is a gradient precipitate architecture which evolves from undeformed ne...
