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

Equal Channel Angular Extrusion (ECAE) method was considered aneffective metal forming procedure to obtain higher toughness, hardness, and smoothtexture. However, the magnitude of these improvements relies on extrusion load andtemperature applied. This research assesses the impact of these extrusion variables onthe mechanical properties and stress distributions in the Aluminum 6063 (Al 6063)produced by ECAE. Specimens of Al6063 alloy were extruded through a locallydesigned 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). Thespeed of the ram was held steady at 5 mm/s. The tensile strength of all extrudedaluminum alloys was assessed with the universal test machine. Specimens of identicalsizes and attributes were also modeled using qform software under extended appliedload and temperature to investigate the distribution of stress in the extrudates. Researchfindings revealed that the temperature of the billet had an impact on the tensile strengthmore considerably than the load applied. Results of simulation revealed that morehomogeneity of stress at a lower magnitude was noticed in extrudates with anincrement in temperature of the billet. The simulation also reiterated the dominance ofthe billet temperature over the applied load on the stress dispersion with a maximumextrusion load of 500 kN at 350 oC temperature, regardless of the load applied. Thisresult 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 notimprove mechanical properties but is a waste of resources.
