Effect of Aging on the Nanostructuring and Strength of a D16 Aluminum Alloy

Resumo

The effect of preliminary quenching and subsequent aging at 190°C for 10 h on the structure and the strength of the D16 alloy subjected to high-pressure torsion at room temperature is studied. The strength of the preliminarily quenched and the preliminarily aged alloy is shown to be comparable despite the fact that a more developed nanostructure forms in the preliminarily quenched alloy during severe plastic deformation. The nature of the alloy behavior is discussed.
