Sažetak
The selection of the material for a particular industrial purpose is made on the basis of knowledge of the material properties and material mechanical behavior under predictable conditions of exploitation. In this sense, the paper deals with the analysis of the mechanical behavior of several metallic materials exposed to different environmental conditions. Experimentally obtained data related to engineering stress-strain diagrams, creep behavior and fatigue of considered materials were analyzed. Experimentally obtained results of the research were drawn in graphic form. Temperature dependency of the material mechanical behavior is visible based on shown curves. For certain material data are listed in the order as follows: ultimate tensile strength (σ_m), yield strength (σ_(0.2)) and fatigue limit (σ_f) at stress ratio R. All data refers to room temperature and they are: 42CrMo4 [(735, 593) MPa, 532 MPa /R=0.25] ; 51CrV4 [(770, 642) MPa, 251 MPa / R=-1] ; 30CrNiMo8 [(696, 355) MPa, 280 MPa / R=-1] ; 18CrNi8 [(613, 458) MPa, 285 MPa / R=-1] ; X6CrNiTi18-10 [(607, 390) MPa, 434 MPa / R=0.25] ; X46Cr13 [(782, 658) MPa, 682 MPa / R=0.25 ; 325 MPa / R=-1]. Data related to Charpy impact energy is also shown.
