Sıfıraltı Sıcaklık Muhafaza Koşullarının Su Verilmiş 2024 Alüminyum Alaşımının Yaşlanma Davranışına ve Şekillendirilebilirliğine Etkisinin Araştırılması

The effect of storage conditions on the ageable 2024 Aluminum alloy, which was stored at different subzero temperatures (-12°C, -15°C, -18°C) after quenching, on the aging behavior and mechanical properties of the alloy at room temperature was investigated by performing hardness, tensile and formability tests. It was observed that the samples stored at -18°C hardened at a slower rate at room temperature compared to the samples stored at -15°C and -12°C. Using the data obtained, linear (Linear) and non-linear (Qudratic and Cubic) models were developed to predict the mechanical properties (hardness, yield and tensile strength) of the 2024 Aluminum alloy, depending on the subzero temperature storage conditions and the time spent at room temperature. It was concluded that the performance of Quadratic models obtained from the results of hardness tests was high, and Linear models could be used for future prediction. The results of the tensile tests showed that the Quadratic models have high performance and usability for future prediction. Finally, the relationship between yield strength and hardness values was examined. A 100% positive relationship was determined between hardness and yield strength values.
