Steel 51CrV4 under high temperatures, short- time creep and high cycle fatigue
The use of a material for a particular purpose is based on its properties. In this sense, the article deals with the analysis of the results of experimental researches performed on steel 51CrV4. Experimental studies included responses ofmaterial at roomand high temperatures aswell as creep and fatigue behaviors of considered material. Responses of the material at room and high temperatures are displayed in the form of engineering stress-strain diagrams. Based on these responses were determined mechanical properties such as ultimate tensile strength (770MPa/20 °C ; 98MPa/700 °C), 0.2 offset yield strength (642 MPa/20 °C ; 60MPa/700 °C) and modulus of elasticity (198 GPa/20 °C ; 37 GPa/700 °C). Short time creep curves showthe behavior ofmaterial at certain high temperatures and stress strevels. Each creep process is performed at constant temperature and the corresponding constant stress. Charpy impact energy (average values: 20 J/20 °C ; 65 J/200 °C) was tested at different temperatures, and consequently, fracture toughnesswas calculated based on these results. Finally, uniaxial fatigue limit in amount of 251 MPa was calculated based on uniaxial high cycle fatigue tests at stress ratio of R = − 1.
