Structure and Mechanical Properties of the Zn-ag-cu Zinc Alloy After High Pressure Torsion

Year: 2022

Type: article

Abstract: Development of new high strength biodegradable materials is one of the hot topics of world science. Recently, interest in zinc alloys for medicine has increased due to compliance with the clinical requirements for the degradation of the material in the body and the participation of zinc in a large number of processes in the body. The microstructure and mechanical properties of the Zn-4Ag-1Cu zinc alloy (wt.%) after high pressure torsion at temperatures 20 °C and 200 °C have been investigated in this paper. An ultrafine-grained structure with a size from 250 nm to 1.5 μm was produced as a result of dynamic recrystallization at HPT processing at 200 ℃, in addition dispersed particleswere observed throughout the HPT sample. The HPT samples processed at temperature of 200 °C demonstrated the ultimate tensile strength of 293 MPa with enhanced ductility of 30%.
