  • Abstract:
    The Portevin-Le Châtelier effect has been investigated by means of an optical extensometer during tensile deformation of Al-3wt%Mg specimens. The propagation of bands with a concentrated deformation has been detected and its velocity measured. A real-time scanning of the phenomenon makes it possible to track the band propagation with an optical sensor.
