Abstract
This study demonstrates that cold pre-forging (CPF) conducted before extrusion is a promising means for improving the mechanical properties of extruded magnesium alloys. The CPF process induces numerous twins in the billet, which in turn provides nucleation sites for dynamic recrystallization during extrusion, leading to an increase in the dynamically recrystallized (DRXed) fraction of the extruded alloy. This process increases the uniformity of the DRXed grain structure, thereby improving the strength and ductility of the extruded alloy.
