This paper deals with the impact of wire manufacturing process on mechanical property development two magnesium alloys, AZ31 and ZX10. For this study, wires were produced different diameters up to 0.2 mm via direct one-step extrusion as a hot forming route directly compared conventional cold drawing routes 0.3 associated heat-treatment. The alloy dependent microstructure is resolved respect underlying recrystallization mechanisms, which determines texture concurrently strength ductility properties wires. experimental results clearly show that process, degree deformation (wire diameter) well itself have major While AZ31, does not enable strong development, in ZX10 enhanced concurrent weak due adjusted dynamic during forming. In contrast, such microstructures cannot be static recrystallization. However, it possible improve significantly by drawing, limited first passes.
