Abstract
The spatio-temporal structure of the Lüders band in artificially aged and recrystallized AMg6 alloys deformed under uniaxial tension at a constant stress rate = const has been investigated using high-speed video recording. A kinetic morphological transition has been revealed between the Euclidean and fractal shapes of the Lüders band due to a transformation of the initial microstructure of the alloy from the precipitation structure formed as a result of the artificial aging to the collective recrystallization structure. The mechanisms of formation of the dendrite-like fractal structure of the Lüders front have been discussed.
