Plastic deformation of Al-Mg alloys were investigated by analyzing the stress-strain curves obtained in uniaxial compression tests at constant loading rate. Experimental results have shown the well-known phenomenon of plastic instabilities -the Portevin-Le Chatelier effect -in these solid solution a
## Akbwt-The occurrence of adiabatic shear bands in metals is analyzed using models based on (i) load instability and (ii) flow localization. In the former case, shear strain concentration is identified with the occurrence of a maximum in the shear stress-shear strain curve. By contrast, the latte
