Microstructure modifications induced by a laser surface treatment in an AA7449 aluminium alloy
Abstract
This work investigates the modification of the precipitate microstructure induced by laser surface treatments in an AA7449 aluminium alloy in T7651 temper. Microhardness maps in the cross-section below the laser lines, as well as maps of the precipitate size and volume fraction obtained by Small-Angle X-ray Scattering, show that a significant precipitate dissolution and coarsening has been induced by the laser treatment. Integrated modelling is …
