Load and Temperature Significance on Tensile Strength and Flow Stress Distributions of Ecae Aluminum 6063

Equal Channel Angular Extrusion (ECAE) method was considered an effective metal forming procedure to obtain higher toughness, hardness, and smooth texture. However, the magnitude of these improvements relies on extrusion load and temperature applied. This research assesses the impact of these extrusion variables on the mechanical properties and stress distributions in the Aluminum 6063 (Al 6063) produced by ECAE. Specimens of Al6063 alloy were extruded through a locally designed and manufactured ECAE die using two factors of extrusion in three levels: temperature (350 oC, 425 oC, 500 oC) and punch load (1000, 1100, and 1200 kN). The speed of the ram was held steady at 5 mm/s. The tensile strength of all extruded aluminum alloys was assessed with the universal test machine. Specimens of identical sizes and attributes were also modeled using qform software under extended applied load and temperature to investigate the distribution of stress in the extrudates. Research findings revealed that the temperature of the billet had an impact on the tensile strength more considerably than the load applied. Results of simulation revealed that more homogeneity of stress at a lower magnitude was noticed in extrudates with an increment in temperature of the billet. The simulation also reiterated the dominance of the billet temperature over the applied load on the stress dispersion with a maximum extrusion load of 500 kN at 350 oC temperature, regardless of the load applied. This result reveals how extrusion temperature increase and load enhance the tensile strength of alloys but in varying degrees. An increase in load above normal level does not improve mechanical properties but is a waste of resources.
