Towards increased strength and retained ductility of Zn-Mg-(Ag) materials for medical devices by adopting powder metallurgy processing routes
Original language description
The development of bioabsorbable zinc-based alloys with tailored mechanical properties and biocompatibility holds great promise for advancing medical implant technology. In this study, Zn–Mg and Zn–Mg–Ag alloys were synthesized using mechanical alloying (MA) followed by extrusion to achieve a combination of enhanced strength, ductility, and corrosion resistance. MA for 4 h produced ultrafine-grained powders incorporating Mg2Zn11 intermetallic phases and oxide particles, which contributed to microstructure stabilization during subsequent processing. Extrusion consolidated these powders into dense materials with a uniform grain size of ~700 nm, exhibiting ultimate tensile strengths up to 435 MPa and elongation to fracture of ~12 %, representing a significant improvement over conventional processing methods.
