Claim 5:
6. A method for preparing a medical implant device, comprising:
fabricating a substrate structured for implanting into a body, comprising:
forming an alloy, comprising:
melting from about 5% by weight to about 11% by weight of lithium and a remainder of magnesium based on the total weight of the alloy, comprising:
high energy mechanical alloying of the lithium and the magnesium;
followed by uniaxial or isostatic compaction; and
followed by sintering,

wherein the alloy is structured to exhibit a co-existence of alpha and beta phases, and
wherein the alloy exhibits one or more of improved ductility and elasticity;
casting the alloy to form a casted alloy; and
extruding the casted alloy to form the substrate in an extruded form.
