The experimentally observed evolution of unstable plastic flow of laser-welded specimens of Al–6Mg–2Li, Al–1.6Cu–1.1Mg–1.8Li, and Al–3.4Cu–0.66Mg–1.5Li aluminum–lithium alloys under different heat treatment conditions after welding was analyzed. A comparison of the jerky flow of alloys with different concentrations of magnesium, copper, and lithium was performed. The effect of copper on the spatial consistency of the localized shear bands formed in aluminum–lithium alloys under unstable plastic flow was studied.
