The effect of local corrosion on the dynamics of macrolocalized deformation bands and the destruction of an AlMg6 aluminum-magnesium alloy was investigated by high-speed video filming of the deformable sample surface. It has been established that a corrosion stain caused by a local effect of sodium hydroxide on the surface of the alloy is an attractor of deformation bands, the interaction of which leads to premature failure and reduction of the ductility of the alloy.
