摘要
The relationship between microstructure and mechanical properties of casing-drilling steels was investigated by means of TEM, SEM and fatigue tests. The results show that the microstructure of the steel with tempered martensite (TM steel) possesses remarkable higher strength and higher hardness values, and the lower strength and hardness of the steel with microstructure of ferrite and pearlite (PM steel) is observed. The Charpy energy absorption values of the steel with ferrite-bainite-tempered martensite (FBM steel) and TM steel are five times higher than that of the PF steel, and the impact fracture of PF steel exhibits a cleavage fracture mechanism, whereas that of the FBM steel primarily follows ductile fracture mechanism. The fatigue crack growth paths and tensile properties of the steel are dependent on its microstructure, the PF steel possesses the highest m value and lowest C value in Paris equation, and the TM steel exhibits the lowest m value and highest C value. ©, 2015, Editorial Office of Transactions of Materials and Heat Treatment.
