Abstract

The microstructure and superplasticity of the thermomechanically proceeded sheets of Al - 3wt.%Mg - 0.25wt.%Zr were investigated. High density of L12-structured fine dispersoids of Al3Zr metastable phase was observed by TEM analysis. Alloy demonstrated high recrystallization resistance at elevated temperature due to Al3Zr dispersoids. The tensile tests were carried out in a temperature range of 440-500 °C and a strain rate of 1×10-3to 1×10-2s-1. The maximum elongation to failure of 370% was observed at 480 °C at the constant strain rate values of 2×10-3and 5×10-3s-1.
