Description
Production of surgical threads for integration of human tissue is an application for magnesium alloys. This paper proposes a two-stage process for production of surgical threads. The first stage is extrusion of tin rods and the second is a warm drawing process in heated dies. The first part of this study focuses on development of numerical models of both stages. Fracture models and flow curves of MgCa08 and ZEK100 alloys were developed. The second part focuses on optimization of the production process. The optimum deformation schedule for both alloys was developed.
