Abstract

Effect of deformation on the corrosion behaviour of Al-1Mn-0.4Fe-0.3Si model alloy was studied after equal channel angular extrusion (ECAE) to different levels and subsequent annealing treatment. During polarisation, cathodic reactivity of the samples increases with the degree of ECAE deformation. Microstructure showed more number of intermetallic particles after ECAE deformation as well as after annealing. ECAE deformation also increased the anodic reactivity. Observed electrochemical behaviour is attributed to intermetallic particles as they good cathodic sites and precipitation of particles deplete manganese from matrix leading to higher anodic activity.
