AbstractMulti-axial compressions/forgings (MAC/F) were conducted at room temperature to obtain severe plastic deformation (SPD) of AA6061 alloy. Microhardness measurements taken across the cross-section of each of the MAC/F processed samples indicated that the hardness distribution is nonuniform during initial compressions/forgings and becomes uniform with subsequent compressions. Microhardness and tensile testing showed that the hardness, yield strength, and elongation of the MAC/F processed material followed similar trends to that for AA6061 processed by equal channel angular pressing (ECAP). The MAC/F material exhibited high strain rate sensitivity and high percentage of elongation to failure in the temperature range of 300-350°C. This observation is in agreement with the high formability of SPD-processed AA6061 over the same temperature range.
