- Abstract
The effect of holes on the band formation and the serrated deformation in planar specimens of aluminum-magnesium alloys AlMg5 and AlMg6 is studied by high-speed video filming of moving deformation bands. It is found that the concentration of an elastic field near a hole causes early nucleation of macrolocalized deformation bands and decreases the critical deformation of the first stress drop. Differences between the spatial-temporal patterns of deformation bands near holes under various deformation conditions are revealed.
