Claim 1:
2. A preparation method of the high-plasticity rapidly-degradable Mg—Li—Gd—Ni alloy according to claim 1, comprising the following technical steps:
A) batching, smelting, and cooling an industrial pure Mg ingot, a Mg—Li master alloy, a Mg—Gd master alloy, and a Mg—Ni master alloy according to above mass fractions to obtain an as-cast alloy;
B) performing pre-extrusion heat treatment, air cooling, and machining on the as-cast alloy obtained in step A) to obtain an extrusion ingot; and
C) performing pre-heating treatment and extrusion forming on the extrusion ingot in step B) to obtain an extruded Mg—Li—Gd—Ni alloy rod.
