Providing optimum forging characteristics of en aw 6082 alloy with minimum deformation energy

Aluminum is the most common element on earth after oxygen and silicon. It is quite difficult to purify and make metallic aluminum from its oxide in natüre. Aluminum is the most widely used material after iron (Fe) among metallic materials. Aluminum alloys are mostly preferred in the aerospace, aviation and automotive industries, especially because of their low density. Due to its high specific strength, aluminum alloys cold provide energy savings.. In this study, production and mechanical properties of aluminum parts used as automotive suspension components were investigated. İt was aimed to goin the same mechanical properties by consuming less energy for aluminum parts producet by hot forging method. The main objective of the this thesis study is to reduce process costs while maintaining the forging mechanical properties. Parameters such as preheating technology, preheat temperature, deformation rate, surface roughness and burr rate were examined comparatively. The effect of production parameters on grain size was determined. Resistance system, infrared heating and induction heating systems were investigated in forging preheating technology. The mechanical properties of the forgings were compared in each preheating technology at 4 different temperatures (450 ° C, 475 ° C, 500 ° C, 525 ° C). In addition, different temperature and preheating technology forged parts with different deformation rates were also forged. In order to see the effect of mold surface roughness, spreading was done by forging with different surface quality molds. The induction heating system is the preheating technology that provides the best material properties using the least energy. As the preheating temperature rises, the material properties are improved for the thermomechanical energy surplus charged to the material. The grain size does not grow at high preheating temperature. When the deformation rate is below 50%, there is no grain coarsening and there is growth in grain size at 70% deformation rate. As the surface roughness of the mold increases, the amount of deformation of the material decreases with the same parameters.
