Extruding Technology and Dies Research of AZ31B Mg-alloy
Hot-extrusion technology of AZ31B magnesium alloy and dies are studied. Extruding experiment shows that AZ31B stock, which has been homogenized at 400℃ holding for 20 hours and then extruded at 380～480℃ and 1.0～2.5m/min extruding speed, has good characteristics for hot extrusion, complex hollow section product can be extruded.
