Microstructure and mechanical properties of a 2091 AlLi alloy—II. Mechanical properties: Yield stress and work hardening

Mechanical properties of a 2091 AlLiCuMg (Zr) alloy are investigated together with those of simpler AlLi (Zr) and AlCuMg (Zr) model alloys. The different contributions to the yield stress are estimated from the microstructure investigated in companion Paper I. Work hardening is described using Ashby's model, but taking into account the strain localization.
