Formability of Al-Mg6.8 alloy has been evaluated experimentally in uniaxial tension and biaxial stretching. Three different structures developed after cold rolling and annealing in the range of temperature from 265 to 320 °C: (I) recovered dual (a + β) phase, (II) recrystallized (a + β) dual phase, and (III) recrystallized a-Al single phase structure, were tested. Samples with recovered structure have shown a lower formability level than the samples with fully recrystallized structure. Formability level assessed through FLD and LDH value, has been a result of complex interaction between work hardening ability and strain rate sensitivity
