Effect of extrusion on mechanical properties and structures of Zn-Mg alloys for biomedical applications

Popis výsledku v původním jazyce

Zn-Mg alloys, in which Mg is an alloying element, are proposed for medical applications as a promising biode-gradable material for temporary implants in orthopedics or traumatology. They can be used to replace nonfunc-tional or damaged tissues. When thehealing process of tissues is finished, the Zn-Mg alloys are gradually de-composed in a human body and a reoperation is therefore unnecessary. Their mechanical properties must be similar to the characteristics of human bones. Large grains are typical forthe structure of cast alloys. Pure Zn and Zn-0.8Mg alloy were cast and subsequently extruded at 300°C. The structure and mechanical properties (Vickers hardness, compressive and tensile strength tests) of the cast alloys were compared with those of theextruded alloys. Pure Zn and Zn-0.8Mg alloy after the extrusion had a fine-grained structure and showed better values of mechanical properties in comparison with the cast alloys.
