Claim 4:
5. The preparation method of the high-plasticity rapidly-degradable Mg—Li—Gd—Ni alloy according to claim 2, wherein a process of step A) specifically comprises: placing the pure Mg ingot, the Mg—Li master alloy, the Mg—Gd master alloy, and the Mg—Ni master alloy in a crucible based on a proportion of the above mass fractions, placing the crucible in a vacuum induction furnace, vacuumizing to 5.0×10−1 Pa, heating to 730° C. under protection of an argon gas until complete melting, performing heat preservation for 10 min, stirring evenly, and scraping away scum on a surface of a melt to obtain an alloy melt; and then closing the vacuum induction furnace, such that the alloy melt is cooled with a furnace temperature of the vacuum induction furnace to obtain the as-cast alloy.
