The effect of fine second-phase non-shearable dispersoids on the grain refinement of aluminium severely deformed by ECAE through routes A and Bc (+90degrees rotation) has been studied using a model Al-0.2%Sc alloy. The microstructure development with strain in the dispersoid containing alloy was compared to a single phase alloy, using high resolution EBSD analysis. The effect of the processing route was investigated for both materials using ECAE die angles of 90 degrees and 120 degrees.
