Sažetak
The proposed paper considers the mechanical behavior of materials usually used in engineering for design and manufacture of highly stressed components. A term behavior involves both the mechanical and elastic properties of the material as well as its creep and fatigue behavior. Between the materials used for the aforementioned purposes are considered the steel alloys such as 30CrNiMo8, 20MnCr5, etc. At different temperatures investigated mechanical properties of the materials were ultimate tensile strength, yield strength and modulus of elasticity, while in the area of mechanical responses were explored / tested creep behaviour and fatigue of the considered materials. Testing results of the material responses are presented in the form of stress-strain curves, creep curves and S-N curves (maximum applied stress versus the number of the cycles to failure). Moreover, while mechanical properties were tested at different temperatures, creep behaviour was investigated at different temperatures and different applied stress levels while fatigue of the considered materials was investigated for prescribed maximum uniaxial stress and for prescribed stress ratio. A general comparison of the obtained results regarding to considered materials have been made.
