Abstract
In the present paper the drawing processes of thin wire of biocompatible magnesium alloys in heated die was investigated. Due to the hexagonal close packet structure magnesium alloys have low plasticity. In order to design the technological parameters the FEM model of wire drawing process in heated die and models of yield stress and ductility were developed. The relationship between technological parameters of drawing and fracture parameters was obtained based on developed models. The maps of possible elongation for MgCa0.8 and Ax30 magnesium alloys were developed using simulations. The draft schedule for final wire diameter 0.1 mm was design assisted with FEM model in experimental part of work. Based on this draft plan the drawing process from initial diameter 1.0 mm to final diameter 0.1 mm in heated die was performed in designed by author’s device.
