Evolution of microstructure dependent corrosion properties of ultrafine AZ31 under conditions of extrusion with a forward backward oscillating die
Abstract
The present work aims to elucidate the role of microstructural changes induced by theextrusion with a forward backward oscillating die, thus verifying a novel approach todeveloping deformation methods for Mg-based alloys at ambient temperature. The mainaim of this study was to show the process which enables the reduction of the hcpstructuredAZ31 rods (40 mm in diameter) to the wires with diameters of 6 mm, 4 mmand 2 mm, without initial preheating of the billet. In contrary to the studies up to date, thesignificant microstructure refinement led to the decline in corrosion resistance of the wireswith 6 mm and 4 mm diameters slightly relative to the original material. The highestextrusion ratio resulted in the formation of an ultrafine, equiaxed microstructure, whichcaused a tremendous corrosion resistance decrease. The significant decline in corrosionresistance of this alloy is a result of the highest number of HAGBs and is promoted by theaccumulation of tangled dislocations. Summing up, the corrosion behaviors of theextruded alloys were mainly affected by the recrystallization stage that occurred duringdeformation, and not by the grain size alone.
