Effects of Ageing on Mechanical Behaviour of Homogenized Twin Rolled 8011 Type Al-Fe-Si Alloy

The use of aluminium-iron alloy sheet is of great importance depending on service requirements for specific application as these materials provide a light weight alternative to steel sheet grades but have limitations in the area of mechanical strength. Exploring ways of improving its mechanical properties particularly its strength has led to development of strength-induce forming processes. In this paper, the effect of ageing on the mechanical properties and morphological structure of homogenized twin rolled 0.85% Fe Al alloy 8011 for potential use in orthopaedic devices was investigated. Mechanical properties of homogenized, cold rolled, hot rolled prior to ageing at 175 0C of twin rolled Al-FeSi alloy was characterized.
