Title: Effect of Pulsed IR Laser Radiation on the Dynamics and Morphology of Deformation Bands in an Aluminum–Magnesium Alloy

Abstract

The dynamics and morphology of deformation bands under the simultaneous effect of mechanical loading and pulsed IR laser radiation on the surface of in aluminum–magnesium alloy AlMg6 were studied by high-speed video recording. The conditions, under which a laser pulse pierces a through hole with a diameter of an order of magnitude smaller than the thickness of a plane specimen, thus inducing the development of a complicated spatiotemporal structure of deformation bands and a macroscopic jump in the tension diagram, were determined. The morphological transitions associated with the transformation of the type, shape, and spatiostatistical distribution of bands with a change in the laser pulse energy density were revealed. The probable mechanism of this phenomenon was discussed.
