Beschreibung
Zusammenfassung:	The preparation method of the high-performance double-phase magnesium-lithium alloy annular part comprises the following steps that a cast ingot is prepared, specifically, alloying elements in the cast ingot comprise Li, Al, Zn and rare earth elements, and an alpha-Mg phase and a beta-Li phase exist in the cast ingot; carrying out homogenization treatment; forging the blank in multiple directions; ring piece forming: quenching with warm water; wherein the warm water quenching refers to cooling the workpiece treated in the step 4 by spraying warm water; after the surface temperature of the workpiece is reduced to 150 DEG C or below, directly immersing the workpiece into a warm water pool or continuously washing the surface of the workpiece with warm water, and after the temperature is reduced to 65 DEG C or below, wiping water on the surface and air-drying; the temperature of the warm water is 45-95 DEG C; according to the preparation method disclosed by the invention, the production efficiency can be improved
