Bioresorbable alloys with a unique ability for biodegradation and resorption with gradual replacement by tissue structures are of increasing interest in implantation medicine. Due to their accessibility and cheapness, zinc-based alloys are considered to be the most promising bioresorbable alloys. The article presents the results of a study of the effect of plastic deformation by the method of equal-channel angular conformal pressing on the microstructure and properties of a zinc alloy Zn-0.8Li-0.1Ca promising for medical use. It has been shown that the pressing leads to the refinement of the structure and the formation of a high complex of mechanical properties: the tensile strength and yield strength are 550 ± 13 MPa and 472 ± 10 MPa, respectively, and the relative elongation is 21 ± 2%. The results of this study can be useful for further developments in the field of creating new materials for implants.References
