Summary

Grain refinement of aluminum by ARB, has been found to be improved and stabilized by the presence of coarse second phase particles. It is thought that second phase particles help prevent a strong Shear and Copper texture developing during ARB processing, by texture ratcheting, which leads to unrefined bands in single phase alloys. Predictions from a Taylor model, based on actual deformation histories for the ARB processed sheet, go some way to confirm this hypothesis.
