Abstract Aluminium is widely used in aircraft and automotive industry. Since aluminium and its alloys have many excellent properties such as low density, good corrosion resistance, machinability and electrical conductivity compared to other materials, high-performance materials, which are both very durable and lightweight, must be used in the manufacture of air and space vehicles. These loads are subjected to thermal shocks with sudden temperature changes in power systems, corrosion due to ambient conditions, and resultant fatigue of different loads encountered in working conditions. The formation and progress of fatigue cracks is one of the most important issues in aircraft design. For example, it has been observed that multiple fractures resulting from the formation and progression of multiple fatigue cracks have resulted in considerable damage.

Aluminum is one of the most commonly found elements in nature and the most commonly used metal after engineering steel. Recently, aluminum and its alloys are an important material for engineers and designers in industry due to their low strength, good thermal and electrical conductivity, increased strength properties and corrosion resistance. Since aluminum and its alloys have many excellent properties such as low density, good corrosion resistance, machinability and electrical conductivity compared to other materials, it is widely used in aircraft and automotive industry. The aircraft and the automotive industry need to use light metals with high strength. High-performance materials, both very durable and lightweight, must be used in the manufacture of air and space vehicles. These loads are subjected to thermal shocks with sudden temperature changes in the power system, corrosion with the effect of ambient conditions, consequent fatigue of different loads encountered in working conditions of these materials. The formation and progress of fatigue cracks is one of the most important issues in aircraft design. Aluminum alloys are economical in many applications. It is used in the automotive industry, in the aviation industry, in the making of machines and devices, as cooking vessels, in the bodies of electronic devices, pressure vessels, cryogenic applications and other fields. Therefore, in this study, the corrosion behaviors of Al-Sn-Zn alloys were determined by applying the mass loss corrosion test. The mass loss-time graph obtained is given in Figure 1 According to the test results, the sample with 70% Sn content undergoes less corrosion over time, while the samples containing Zn and Al undergo more corrosion over time.

Abstract Aluminum, which is in the light metal category due to the development of technology and the technical features it possesses, is widely used in many fields of industry. In practice, the ratio of the strength to the weight (specific strength property) is very large; the soft and one-third the weight of steel. When alloying elements are added, the mechanical properties can be increased to be comparable to steel; this makes aluminum usable for medicine, construction, food, automotive and aerospace industries. All the hardening elements added to aluminum reduce thermal and electrical conductivity and elongation. The applied heat treatments change plasticize and hardness. The manganese has an effect of increasing the toughness and ductility properties, but it has become an essential element in the secondary additions by increasing the tensile strength without reducing the corrosion resistance. In this study, the mechanical properties of alloys with different compositions of Al-based Al-Mn alloys were determined by Vickers Hardness Tester, Tensile Test and the effect of heat treatment was discussed. Accordingly, the average hardness values of Al-x Mn (x = 0.1, 0.2, 0.3) alloys were measured as 47.7, 50.8 and 53.3 for the samples not subjected to heat treatment and 50.2, 54.1 and 81 for the samples subjected to heat treatment, respectively. According to the tensile test results, the order of Al-x Mn (x = 0.1, 0.2, 0.3) alloys is max. tensile strength 87.9, 97.4, 101.23 MPa, heat treated samples 101.15, 106.6, 125.4. SEM, EDX and XRD and microstructural and surface morphologies related to the composition were investigated.
