Studies on the stress corrosion behaviour of aluminium 6061 / red mud metal matrix composites

Composite materials are very much popular nowadays with respect to their decreased density and improved corrosion and mechanical characteristics. They are in demand in many engineering and manufacturing fields. In this work composite materials of aluminium 6061 reinforced with Two, Four and Six weight percentage of red mud particulates are developed by stir casting process. They were subjected to studies on stress corrosion behaviour in hydrochloric acid and sodium chloride mediums at different temperature and exposure timings with different concentrations using specimens machined from castings as per ASTM standards. In all the mediums it was found that composite materials exhibit improved corrosion resistance on comparison with matrix alloy. Hence composite materials are having extensive applications than matrix alloy. © 2022
