Processing Age-Hardenable Alloys by Equal-Channel Angular Pressing at Room Temperature: Strategies and Advantages

Abstract:

The effect of the combination of natural aging and severe plastic deformation (SPD) produced by Equal-Channel Angular Pressing (ECAP) on the microstructure, the strength, as well as the ductility of age-hardenable AlZnMg alloys was investigated. A strategy is proposed for the processing of these “difficult-to-work” alloys at room temperature. Several advantages such as strengthening, precipitation-accelerating and ductility-improving effects of ECAP at room temperature are also shown and discussed in this work.
