The effect of solute content and heat treatment on occurrence of the P-L effect were investigated in AI-Ag alloys. The activation energies estimated from values of the critical strains were nearly equal to that for solute migration in AI-MO alloys, which means that the P-L effects in AI-Ag alloys we

The PortevinLe Chatelier effect is assumed to be associated with an inverse strain-rate effect. A numerical analysis of a rheological model is then conducted, where a dashpot is assumed to exhibit a stress versus strain-rate relation with a region of negative slope, i.e. an inverse strain-rate effec

The presence or the absence of the Portevin-Le Chatelier effects in Cu-P, Cu-Ti and Cu-Si alloys were investigated as functions of solute content, temperature and heat treatment. The serrated flows were observed in all the systems but in the Si bearing alloys it appeared at higher solute content and
