Advanced Zinc–Magnesium Alloys Prepared by Mechanical Alloying and Spark Plasma Sintering

Popis výsledku v původním jazyce

Zinc and its alloys are considered as the promising materials for the preparation of the 11biodegradable medical devices (stents, bone fixation screws), due to their enhanced biocompatibil- 12ity. These materials must achieve an ideal combination of mechanical and corrosion properties that 13can be influenced by alloying or thermomechanical processes. This paper presents the effects of 14different mechanical alloying (MA) parameters on the composition of Zn-1Mg powder. At the same 15time describes the influence of preparation by MA on Zn-6Mg and Zn-16Mg alloys. The selected 16powders were compacted by spark plasma sintering (SPS) method. Subsequently their microstruc- 17tures were studied, and mechanical properties were tested. The overall process led to a significant 18grain refinement (629 ± 274 nm for Zn-1Mg) and the formation of new intermetallic phases (Mg2Zn11, 19MgZn2). The compressive properties of the sintered samples were mainly related to the concentra- 20tion of the alloying elements, where an increase in concentration led to an improvement in strength 21but a deterioration in ductility. According to obtained results, the best properties were obtained for 22Zn-1Mg alloy.
