Abstract
The use of Zn-based alloys as biomaterials is becoming increasingly common due to their biodegradability and biocompatibility. However, while the strain value is important for the forming of the alloy, relatively low mechanical properties can degrade the performance of the alloy. It was found that the mechanical properties of this alloy, which is usually obtained by casting, were low when the alloy was shaped by chip removal. Based on this, its mechanical properties were improved by cold ECAP. In this study, FEM analyses were performed before the experimental process and the variation of the mechanical properties of the alloy depending on the ECAP process parameters up to 4 passes in 4 different routes and passes were investigated cold without dynamic recovery. The mechanical properties of the Zn-Cu-Mg alloy were obtained with Equal Channel Angular Pressing (ECAP) with Equal Channel Angular Pressing (ECAP) in square section process parameters with a corner angle of 135o. According to the results obtained from FEM analyses, a certain amount of rotation may occur from the square-section ECAP processes and stress concentration may occur at the edges and corners.
