Effect of pre-aging on the microstructure and strength of supersaturated AlZnMg alloys processed by ECAP
Effect of pre-aging on the microstructure and strength of supersaturated AlZnMg alloys processed by ECAP
This work is focused on the effect of the combination of natural aging and severe plastic
deformation (SPD) produced by Equal-Channel Angular Pressing (ECAP) on the microstructure and
strength of supersaturated AlZnMg alloys. Following a solution heat-treatment and quenching into
water at room temperature, samples were naturally aged for different time periods and then
processed by ECAP. The microstructure and mechanical properties of these samples are described
and discussed. This investigation leads to proposing an interesting application of ECAP for
supersaturated alloys. Using the shear bands created by ECAP in only one pass and applying
appropriate subsequent aging treatments, composite-like microstructures can be achieved in
conventional age-hardenanble Al alloys.

Abstract
This work is focused on the effect of the combination of natural aging and severe plastic
deformation (SPD) produced by Equal-Channel Angular Pressing (ECAP) on the microstructure and
strength of supersaturated AlZnMg alloys. Following a solution heat-treatment and quenching into
water at room temperature, samples were naturally aged for different time periods and then
processed by ECAP. The microstructure and mechanical properties of these samples are described
and discussed. This investigation leads to proposing an interesting application of ECAP for
supersaturated alloys. Using the shear bands created by ECAP in only one pass and applying
appropriate subsequent aging treatments, composite-like microstructures can be achieved in
conventional age-hardenanble Al alloys.
