文摘

Microstructural effects on work-hardening of a 6xxx aluminium is studied. A semiphysical work-hardening model that account for precipitate volume fraction is presented. Temperature dependence is also included thanks to a isokinetic precipitate evolution. Neutron diffraction allows to validate residual stresses of the welding simulation.
