【 摘 要 】

This study considers changes introduced by the grain size variation into mechanical properties and corrosion behavior for Mg-1%Zn-0.2%Ca bioresorbable alloy for implant applications. The variation of the grain size was achieved by high pressure torsion (HPT) followed by annealing at different temperatures. It was shown that a simultaneous increase of the polarization resistance and the alloy microhardness can be achieved after HPT followed by annealing at 250 °C compared to coarse grained cast alloy. Therefore, these treatment conditions can be considered as promising for development of bioresorbable Mg alloy implants.
