Effect of Extrusion Parameters on Microstructural and Mechanical Properties of EN AW 6063

Abstract

Extrusion is a plastic forming process that uses cylinder shaped raw materials. Direct extrusion method which is one of the two extrusion types, manufactures products by forcing billets with a ram throughout the dies. By the effect of high deformation amount and elevated temperature products called profiles acquire their final properties. Extrusion parameters can be classified into two main topics as temperature and deformation based and these parameters highly affects the final properties of extruded products. With this concept, effect of extrusion speed and billet heating temperature on properties of EN AW 6063 alloy were investigated in this study. Precise characterization techniques were utilized to evaluate microstructural and mechanical properties of the samples. Additionally, computer aided simulation software called QForm was used for simulation of extrusion process and final material properties and outputs of software were compared with experimental results.
