Compose a 2750 words assignment on measuring tensile properties of metal specimens
The outcome of the tensile tests confirmed that the Steel 1018 was stronger than the Aluminum 6061-T6, Aluminum 2024-T4, and also Steel A36. Steel 1018 had the average maximum ultimate tensile strength and Steel had the average maximum ultimate tensile strength, they both had a greater modulus of toughness, had larger true fracture strength, and had a higher yield than the Aluminum 2024-T4 and also Aluminum 6061-T6. This proves that Steel 1018 and Steel 36 are more ductile because of their percent reduction in the area ranging to 50.50% and a percent elongation ranging to 17.6% compared to Aluminum2024-T4 and Aluminum 6061-T6.
Steel is stiffer meaning it deforms less for a given load but it is also more ductile because it deforms more than aluminum prior to final rupture. Therefore, it is an ideal choice for engineers. However, aluminum is lighter and less susceptible to corrosion.
For the selection of engineering materials, standard tensile testing parameters are useful. It helps in the choice of the majority of suitable materials for many projects and to develop new techniques to alter the material’s properties so that it can be customized and the material can be used for the particular application.
The purpose of this experiment is to determine the tensile strength of Steel 1018, A36 Steel, 2024-T4 Aluminum, and Aluminum 6061-T6 using the Tinius-Olsen machine and data acquisition software. Also, the strength and several elastic and inelastic properties of the stated metal specimens are measured and compared. .Finally, a comparison of the recorded values of each property of the metal specimens with the values reported in the literature and observing and comparing the variations in the performance of materials in load.
To achieve the objectives, 16 metal specimens – 4 specimens each of A36 steel, 1018 steel, 6061-T6 aluminum, and 2024-T4 aluminum were tested in uniaxial tension to failure. . Load and strain data from the tests were used to determine the material properties of the specimen and results were compared among specimens and to reference values.
