Abstract

The effect of fine, non-shearable, dispersoids on the grain refinement of aluminiumalloys, severely deformed by ECAE, has been studied using a model Al-0.2%Sc alloy, duringdeformation by Routes A and BC (+90degrees rotation) using a 120??, or 90??, die. The microstructure in the dispersoid-containing alloy was compared to a single-phase alloy using high resolution EBSD analysis. With Route A the presence of fine dispersoids was found tosignificantly retard the development of new high-angle grain boundaries and the formation of a fine grain structure, by homogenising slip and inhibiting microshear bands. This difference was greatly enhanced, using Route BC. Similar results were obtained with the two die angles, but with Route A refinement tended to be slightly less effective when using the 90?? die.
