Abstract

Magnesium alloys are indicated as potential biodegradable biomaterials, since they have good biodegradability, biocompatibility and satisfactory mechanical properties. When compared to metal alloys used in permanent implants, ceramic and polymeric biomaterials, magnesium alloys are characterized by low specific mass and better results in load applications due to the combination of high mechanical resistance and fracture resistance. In addition to modulus of elasticity and flexural strength close to the natural bone. Aiming at a future application as a biodegradable biomaterial, this project focus on the production of the Mg-3,4Dy-0,2Zn-0,4Zr alloy by melting, processing by hot-rolling and microstructural characterization. It is expected that from the results found it will be possible to obtain a biodegradable magnesium alloy for application in non-permanent implants. (AU)
