Grain size in Mg alloys: recrystallization and mechanical consequences
journal contribution
posted on 2007-01-01, 00:00 authored by Matthew BarnettMatthew Barnett, Dale Atwell, Aiden BeerAiden BeerThe present paper examines the development of grain size during the recrystallization of magnesium alloys and the influence the grain size has on the mechanical response. In magnesium alloys grain refinement improves the strength-ductility balance. This simultaneous increase in both strength and ductility is ascribed to the impact the grain size has on deformation twinning. The mechanisms by which the grain size is established during hot working are shown to be conventional dynamic recrystallization followed by post-dynamic recrystallization. The role of alloying additionon both of these reactions is briefly considered.
