文摘
Creep behavior is one of the most critical factors determining the failure life of components at elevated temperature. Turbine rotor shaft is subjected to such elevated conditions. The creep behavior of rotor grade steel 28CrNiMoV59 was studied at elevated temperatures from 550 to 650 °C and at stress levels varying from 120 to 300 MPa. Tensile tests were conducted to determine the basic properties. Microstructural and chemical analyses were performed to characterize the as received material. Creep rupture data were determined from experimental results. These results were used to calculate the creep constants at elevated temperature which are used in time–temperature parametric (TTP) methods. Different TTP methods like, Larson–Miller, Orr–Sherby–Dorn and Manson–Haferd, were analyzed to check their suitability for extrapolation of creep rupture data of (28CrNiMoV59) steel.
