Abstract Scope |
In recent years, surgical sutures are made from bioabsrbable polymers due to the benefit for avoiding removal operation. Magnesium alloys are possible candidates for bioabsorbable sutures because of their biocompatibility and degradability. Since the drawing is suitable for manufacturing a metallic fine wire, we clarify the effect of additive elements, calcium or zinc, on mechanical properties of drawn magnesium wires. Binary alloys of Mg-Ca (0.1 to 0.3 at%) and Mg-Zn (0.1 to 0.3 at%) were cast followed by extrusion. The extrusions were drawn to fabricate a fine wire having a diameter of 0.2 mm. Tensile tests were conducted for the wires. As a result, yield stress increased with increasing the content of solute elements, while the work hardening rate and tensile ductility were varied with the kind of additive element. Inspect of the drawn microstructure revealed that the additive element plays an important role for microstructure evolution in magnesium. |
