Abstract

Nanograined structures with an average grain size of similar to 85 nm have been achieved in solution hardened AZ31 magnesium alloy by two-pass friction stir processing under rapid heat sink in which the second pass has a lower heat input. The mean hardness of the nanograined region reaches similar to 1.5 GPa (or 150 H-v), about three times that of the matrix. The evolution of the nanograined structure is also investigated.
