Abstract

In this work, a Zn-1.6Mg alloy was studied. The alloy composition was chosen according to the results of our previous work, which was focused on the research of biodegradable materials. The mechanical properties of such cast alloy are similar to the characteristics of human bones. Moreover, the Zn-1.6Mg alloy satisfies the requirements of biocompatibility. These facts determine the alloy for use in medicine as a suitable material for temporary implants. The alloy was studied in three different stages of processing: a cast form, an extruded form and, finally, a rapidly solidified alloy prepared by melt-spinning with the following hot extrusion. The main aim was to prepare a Zn-1.6Mg alloy with fine structure which ensures the improvement of mechanical properties. Microstructure was evaluated by optical and electron microscopy; mechanical properties (compressive strength, hardness) were measured and corrosion rate was evaluated in model physiological solution.
