| Abstract Scope |
Magnesium alloys are a promising candidate material for a range of bioresorbable medical devices. Their application has been limited due to their relatively poor mechanical properties at room temperature. However, these bioresorbable devices will be deployed in vivo at 37°C. Therefore, this study investigates the sensitivity of the mechanical properties of three Mg-4Li-xY (x=0.5, 1 and 2wt%) alloy wires at 37°C and at temperatures up to 100°C during tensile testing. Each of the alloys exhibit decreased strength and increased ductility at 37°C and higher temperatures. Increasing the Y content of the alloy decreased the sensitivity of the mechanical properties to temperature. Consequently, when developing Mg alloys for device specific applications, the sensitivity of the alloy to body temperature should be considered. Additionally, the temperature sensitivity of this new alloy series can be exploited when considering application in devices which require high ductility, such as balloon expandable vascular scaffolds. |
