Abstract

The study investigated the influence of steel die parameter and the microstructural evaluation of AA 6063 aluminum alloy extruded at room temperature using different die entry angles. Mild and tool steel dies of entry angles of 15o, 30o, 45o, 60o, 75o and 90o were used to extrude the work sample. Microstructural analysis, coupled with ram velocity, elongation, hardness, and maximum extrusion pressure of the extruded samples, were de-termined. It was observed that theaximum extrusion pressure required for extrusion and hardness of extruded samples increased with increasing die entry angle .Experimental results show that aluminum alloy deforms better when the die material is made of mild steel with die entry angles of 45o, 75o and 90o as compared to tool steel
