Abstract : A report is provided of progress in studying cyclic deformation of precipitation-hardened alloy in a project supported by the army. This work concentrated on the stability of precipitates under cyclic deformation (Al-Ag, Al-Cu systems) and the strain-localization behavior of alloys containing shearable precipitates (Al-Cu, 0'') and non-shearable precipitates (Al-Cu, 0'). Furthermore, the relationship of cyclic response in such simple systems to that of commercial alloy was also studied. The main results are reported.
