Abstract: The dynamics and morphology of deformation bands and the discontinuous deformation under local action of pulsed infrared fiber laser radiation on the surface of aluminum–magnesium Al-6%Mg alloy have been studied by high-speed video recording techniques. Conditions under which laser action leads to the formation of macrolocalized deformation bands and deformation jumps of several percent on the stress–strain diagram are experimentally established. A possible mechanism of this phenomenon is discussed.
