Investigation into the influence of rolling strain and into the variation of properties and structure during reheating intervals between rolling passes in the thermomechanical processing of an Al-9.89Mg-0.09Zr alloy (composition in weight percent) was conducted. Superplastic ductilities up to approximately 1120 percent were achieved by processing to a total strain of 2.5 utilizing a reheating interval of 30 minutes. Conversely, rolling to lesser values of strain with the same reheating interval or rolling to a strain of 2.5 and using a 5 minute reheating interval produced ductilities less than 400 percent. A strong correlation was demonstrated between results achieved and a qualitative model for continuous recrystallization during thermomechanical processing previously proposed.
