The influence of precipitation hardening on the characteristics of serrated yielding in an Al-IMg-Si alloy has been investigated. The critical strain at the onset of serrated yielding was increased by ageing and for ageing times longer than 6 hr at 180°C serrated yielding was not observed. The strai
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 unstable plastic flow caused by the Portevin-Le Chatelier effect is studied experimentally. Non-local effects due to strain heterogeneity are addressed by comparing the statistical and multifractal properties of tension and compression deformation curves of an AlMg alloy. Power-law statistical d
