THEORETICAL ANALYSIS OF THE AZ31 MAGNESIUM ALLOY DEFORMATION PROCESS BY A MODIFIED METHOD OF ANGULAR EXTRUSION
The paper presents the results of the numerical modeling of a chosen magnesium alloy deformation process by a modified method of angular extrusion (AE). The research was made using a die with a circular cross-section, where the channels were arranged at right angles relative to each other. The modification concerned the differing values of applied unit strain obtained by changing the material enter/exit diameter ratio. The extrusion process was analyzed for several temperature-velocity variants. The aim of this work was to determine the most favorable conditions of the extrusion process that result in the most uniform stress and strain distribution in the material.
