Biomedical magnesium alloys have received attention in the last decade for their potential to degrade safely in the human body, facilitating temporary structural implants without the need for removal. Many alloys evaluated for this purpose are limited by potentially unsafe alloying elements, low strength, and/or high corrosion rate. Here we evaluate a Mg-1.0Ca-0.5Sr alloy, thermomechanically processed by hot extrusion. It is shown that excellent strength (in tension and compression) and low degradation rate (as measured in a simulated body fluid) resulting from microstructural modification of the extrusion process. Structure – property relationships are established, as well as property comparisons to other similar alloys.
