Abstract
This experimental study examined the impact of die shape on the mechanical characteristics of the AA7075, the aluminum alloy, extruded by hot direct extrusion. These characteristics include the extrusion load, hardness and compression tests, and stress-strain curve. Three alternative widths of the extruded metal exit zone (16, 18, and 20 mm) and three different die angles (15°, 30°, and 45°) were considered in the experiments. According to the findings, the extrusion load for the extruded items was the highest at an angle of 30° and the lowest at an angle of 15°. In terms of the hardness test of extruded materials specimens, the hardest areas were located at the outer circumference for all extrusion diameters and angles. Although the extruded samples’ compression test results showed variations in the samples’ loads before and after extrusion, it was also noticed that some of the other samples’ stress and strain curves converged while others had only slight differences.
