Room temperature engineering stress-engineering strain curves of the initial AZ31 alloy sample (not deformed) and the DSR-deformed AZ31 alloy samples (route A and route D) (a). Yield strength (YS), ultimate tensile strength (UTS) and elongation-to-failure of the initial AZ31 alloy sample (not deformed) and the DSR-deformed AZ31 alloy samples using route A and route D (b). Yield strength versus elongation-to-failure of AZ31 alloys deformed by equal channel angular pressing (ECAP)2,16,17,18,19, accumulative roll-bonding (ARB)3 and differential speed rolling (DSR)20,21,22,23,24,25,26 (c). Specimens geometry used for the tensile tests (d).
