Abstract
The microstructure, mechanical properties and superplasticity indices of sheets of aluminum alloy Al – 3% Mg with 0.3% Zr and 0.1% Ti are studied. Use of low-temperature homogenizing (at 360°C) and two-stage hot rolling (at 360 and 420°C) with intermediate annealing at 420°C (3 h) provides quite good thermal stability of alloy grain structure and improved strength properties at room temperature. The alloy exhibits signs of superplasticity with a constant deformation rate of 5 × 10–3 sec–1 and retains a virtually unrecrystallized structure after 200% deformation.
