摘要

The effect of multi-cycle combined processing (ЕCAP combined with ultrasonic exposure) on the structure, mechanical, and corrosion properties of the bioresorbable Mg‑8.6Zn‑1.2Zr alloy is examined. It is shown that this deformation processing scheme allows achieving a tensile strength of 305 MPa. There is a tendency for the corrosion rate to decrease with an increase in the number of deformation cycles, and a value of 3.0±0.2 mm/y is achieved. This is attributed to an increase in the proportion of recrystallized grains in the Mg‑8.6Zn‑1.2Zr alloy structure.
