Enhanced Mechanical Properties in 6082 Aluminum Alloy Processed by Cyclic Deformation

Aging heat treatment is the most commonly used strengthening method for Al–Mg–Si alloys since high-density precipitates will be formed to hinder the movement of dislocations. In the current work, room temperature cyclic deformation was attempted to strengthen the alloy. We compared tensile test resu...
