Abstract: The disclosure discloses the forging process of a magnesium alloy wheel hub comprises the following steps: step 1, heating a magnesium alloy bar to 350-420° C. and keeping the temperature for 20 minutes; step 2, forging and forming the bar under a 6000-ton forging press, and controlling the forging process in sections. The forging process of the disclosure adopts sectional control, different forging process parameters are adopted in different forging stages, so that magnesium alloy bars can exert maximum forgeability in different deformation stages, make magnesium alloy deformation process more continuous, make forging process easier, obtain forged magnesium alloy wheel hub with excellent properties, and greatly improve forging process and processing efficiency.

Abstract: The disclosure discloses a magnesium alloy for wheels, comprising in mass percentage: Al: 2-3.0 wt. %; Zn: 0.5-1.0 wt. %; Mn: 0.3-0.5 wt. %; Ce: 0.15-0.3 wt. %; La: 0.05-0.1 wt. %, the balance is Mg. The magnesium alloy of the present invention takes Al element and Mn element as main alloying elements, supplemented by trace Ce and La elements as alloying process, and the nano-scale Mn-rich precipitated phase obtained during homogenization and the segregation of rare earth elements Ce and La at the interface and grain boundary of Mn-rich precipitated phase are used to inhibit the coarsening during extrusion and forging, so as to improve the strength and plastic deformation ability of the alloy.
