Effect of extrusion ratio and die angle on the microstructure of an AA6063/SiC composite

Abstract

Abstract Manufacturers often employ the extrusion process to form an object with any cross-section. An experiment was carried out to examine the effect of die angle on the quality of the extruded product. The four types of extrusion dies were designed for finding the desirable quality of aluminium composite extruded billet. The five percentages of the Silicon carbide have been chosen as reinforcement with aluminium alloys. Further, the various extrusion dies configurations were considered as 12:8, 12:2, 12:4, and 8:4 for producing the extruded billets. In addition, the die angles that correspond to the required minimum extrusion load were determined. According to the findings, 12:8 extrusion configurations with a 30° die angle produced the desired quality billet and fine grain structure of extruded product with reduced extrusion load. The extruded billet surface quality was analyzed by scanning electron microscopy.
