A magnesium rare earth alloy wheel hub capable of rapid high-temperature solid solution treatment and its preparation method are disclosed. The magnesium alloy composition by weight percentage is: Nd: 1.4–2.0%, Gd: 2.0–3.0%, Zn: 0.04–0.20%, La: 0.1–0.4%, Zr: 0.3–0.7%, total impurity elements ≤0.2%, with the remainder being Mg. La, Nd, and Gd elements are compositely added to the magnesium alloy. La enhances the strengthening effect of the Mg-Nd precipitate phase, combined with the dispersion strengthening effect of the introduced Mg-La phase. Simultaneously, the Mg generated by La in the alloy is utilized... 12 The pinning grain boundaries of the La phase effectively suppress grain coarsening in magnesium alloys, thus avoiding the reduction in mechanical properties caused by increased solution treatment temperature. This ensures that the mechanical properties of magnesium alloy wheels prepared using high-temperature solution treatment meet the requirements for automotive wheels. It also significantly shortens the high-temperature solution treatment time in the manufacturing process of magnesium alloy automotive wheels, resulting in a marked improvement in production efficiency and a substantial reduction in manufacturing costs, thus meeting the requirements for mass production of magnesium alloy automotive wheels.
