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.

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.
