Description	Magnesium and its alloys are attractive to automobile and aerospace industry and may also find applications in medicine fields as biodegradable implants. Accounting for both metallurgical and biological aspects, new magnesium based alloy containing zinc and calcium in concentrations 1-4 wt% and 0.4 wt%, respectively, have been designed. As one of the most effective ways to improve mechanical properties of Mg alloys via reduction of grain size, equal channel angular pressing (ECAP) has been used. The average grain size of alloys was reduced in this way to units of mým after four passes. The microstructure of the alloy was characterized by light and electron microscopy, and its mechanical properties were examined by tensile and microhardness measurements. It was shown that the microhardness as well as ultimate tensile strength and elongation increased with decreasing grain size. In addition, the influence of varying zinc content and heat-treatment on processing of the alloy by ECAP was examined. Basic exposure tests were carried out in physiological solution and reveal the positive influence of Ca on corrosion resistance of the alloy. Preliminary results show a good potential of MgZnCa based alloy as a new biomedical material.
