STRUCTURE-SENSITIVE TRANSITION BETWEEN EUCLID AND FRACTAL FORM OF LUDERS BAND
Spatio-temporal structure of Luders band in the thermal aged and recrystalized aluminum-magnesium AMg6 alloy, deformed with the constant velocity of increasing of applied stress = const, is investigated by the high-speed videotaping. The kinetic morphology transition between Euclid and fractal forms of Luders band during the change of initial microstructure of alloy from precipitation structure to recrystallization fractal structure is revealed. Mechanism of forming of dendrite-like fractal structure of Luders front is discussed.
