Abstract
Different equal channel angular pressing (ECAP) processing routes have been employed to
investigate the flow plane microstructures in a hypoeutectic Al–7wt%Si. In the as-cast condition,
this alloy exhibits equiaxed primary aluminum dendrite cells embedded in an Al–Si eutectic
constituent. The observed microstructures have been compared to the predicted distortion of a
volume element expected during idealized ECAP. The effect of different processing routes on the
microstructure refinement, degree of homogenization of second phase particles, and associated
mechanical properties are discussed.
