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 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
