This study aims to give theoretical information about the production and characterization of
mechanical properties of 2024 aluminum alloys. AA2024 alloy; It consists of components such as
aluminum, copper, magnesium and manganese, and the production of the alloy is usually carried out
by different methods such as casting, rolling, extrusion and powder metallurgy. The choice between
production methods should be made by considering the purpose and properties of the alloy. While
the casting method is used for the production of large-sized parts, the rolling method is suitable for
the production of thin sheets and strips, and the extrusion method is suitable for the production of
profiles and pipes of various shapes. The powder metallurgy method, on the other hand, is carried
out by shaping the powdered components of the alloy with a special pressing process and then
sintering at high temperature. Alloys produced by this method exhibit high strength properties with
their high density and homogeneous microstructures.
The mechanical properties of AA2024 alloy are generally determined using various
characterization methods such as tensile test, hardness measurement and fatigue life tests. The
tensile test is used to determine the tensile strength, tensile elongation ratio and elastic tension
properties of the alloy. The hardness measurement is used to determine the surface hardness of the
alloy. Surface hardness can be performed using Brinell, Vickers and Rockwell hardness
measurement methods. The fatigue life test is used to determine the fatigue strength of the alloy. In
this test, the fatigue life of the specimen under repetitive loads is determined. The mechanical
properties of AA2024 alloy may vary depending on production methods, alloy components,
temperature and environmental conditions. Therefore, the mechanical properties of the alloy must be
optimized for a particular application. 2024 aluminum alloys produced by powder metallurgy
method are expected to exhibit high density, homogeneous microstructure and high strength
properties as a result of hardness, tensile and fatigue tests. |
