A magnesium alloy of the present invention has a structure, comprising: 0.5-2.0 wt % of Zn; 0.3-0.8 wt % of Ca; at least 0.2 wt % of Zr; and the remainder comprising Mg and unavoidable impurities, wherein a nanometer-sized precipitate comprising Mg, Ca and Zn dispersed on the (0001) plane of a magnesium matrix, thereby achieving both formability and strength in a range of temperatures including room temperature.

Examples of an alloy injection molded liquid metal substrate are described. In an example, an alloy injection molded liquid metal substrate includes a liquid metal substrate and an alloy injection molded on a first surface of the liquid metal substrate.

The invention relates to biodegradable, metal alloys, methods for their preparation and applications for their use. The alloys include magnesium and other components, such as, yttrium, calcium, zirconium, and zinc. These elements are alloyed together in specific combinations and amounts in order to achieve an alloy having desired properties and characteristics. In certain embodiments, strontium or cerium may be included as an additive. The resulting alloys are particularly suitable for forming various medical devices for implantation into the body of a patient.

A Mg—Li—Al—Zn alloy is disclosed. The Mg—Li—Al—Zn alloy comprises, in weight percent: 5-15% Li, 1.5-9.0% Al, 0.5-1.5% Zn, 0.4-1.3% Y, 0.18-1.01% Nd, 0.09-0.65% Ce, and the balance Mg and incidental impurities. Experimental data have proved that, this novel Mg—Li—Al—Zn alloy has a flashover temperature in a range between 620° C. and 700° C., such that the flashover temperature of the specifically-designed Mg—Li—Al—Zn alloy is greater than that of commercial LAZ521, LAZ721, LAZ771, LAZ921, and LAZ1491 alloys. Therefore, the Mg—Li—Al—Zn alloy of the present invention can be processed to be a structural article through air melt and casting process.
