For the purpose of achieving this aim, evaluation of values such as ultimate tensile strength, yield strength, percentage of elongation and area reduction, fracture strain and Young's Modulus was done once the specimens were subjected to uniaxial tensile loading. Investigation of the engineering and true Stress-strain relationships of three specimens in conformance with ASTM E 8 – 04 is the aim of this paper. Its main objective would be to determine the properties relevant to the elastic design of machines and structures. The most commonly accepted method in evaluation of the mechanical properties of metals would be the tension test.
