1. A method for preparing a medical implant device, comprising: fabricating a substrate structured for implanting into a body, comprising: forming an alloy, comprising:
I melting 9.00% by weight of lithium, 0.96% by weight of zinc, and 0.01% by weight of aluminum, and a remainder of magnesium based on the total weight of the alloy, or
II melting about 8.99% by weight of lithium, 0.87% by weight of zinc, 1.07% by weight of aluminum, and a remainder of magnesium based on the total weight of the alloy, or
III melting about 6.11% by weight of lithium, 0.92% by weight of zinc, 0.04% by weight of aluminum, and a remainder of magnesium based on the total weight of the alloy,
wherein the alloy of I, II, or III is structured to exhibit a co-existence of alpha and beta phases,
wherein the alloy of I, II, or III exhibits one or more of improved ductility and elasticity;
casting the alloy of I, II, or III to form a casted alloy; and
extruding the casted alloy to form the substrate in an extruded form.
