Abstract
The use of Zn-based alloys as biomaterials is becoming increasingly common due to their biodegradability and biocompatibility. However, although the strain value is important for the forming of the alloy, relatively low mechanical properties can degrade the performance of the alloy. The mechanical properties of this alloy, usually obtained by casting, were found to be low when the alloy was formed by machining. Based on this, its mechanical properties can be improved by cold ECAP. Before the ECAP process can be carried out, moulds need to be produced. The production of these moulds is a very costly and time consuming process. Due to an overlooked detail, the moulds do not work and all financial means and time are consumed. In order to prevent this situation, the stress, strain, flow and temperature parameters of the alloy were investigated by FEM analyses in this study. In addition, during the ECAP process, it is possible that the metal passing through the channel elbow will be stressed and folds will occur inside. FEM analyses were performed to prevent this situation. In addition, while the alloy is deformed in the square section, it may undergo some torsion due to the angle and inhomogeneous friction. In order to overcome these, FEM analyses were performed and the pre-production behaviour of ECAP moulds and Zn-based alloy were investigated.
