Abstract: Based on the analysis of the data of high-speed video recording of the surface of the deformed aluminum-magnesium alloy 5556, it has been found that the unstable plastic deformation associated with the deformation band dynamics tends to deformation chaos with increasing deformation. It has been shown that the ductile fracture of the 5556 alloy with a recrystallized structure should be considered as a global self-organization in a nonlinear nonequilibrium system being in the state of deterministic chaos.
