  • Magnesium alloy for wheel and preparation method thereof
    Publication number: 20230074156
    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.
