microstructure and mechanical properties of crmov steel
The effect of austenitizing temperature on mechanical properties of the mixed bainite - martensite microstructure in CrMoV steel was studied in the present work.
Resume In this contribution microstructure degradation of a steam tube is analysed. The tube is made of CrMo creep resistant steel and was in service under creep conditions at temperature 530°C Effect of Austenitizing Temperature on Mechanical 3.2. Mechanical properties In order to study the effect of lower bainite - martensite mixed microstructure on the mechanical properties of the CrMoV steel,
The effect of austenitizing temperature on mechanical properties of the mixed bainite - martensite microstructure in CrMoV steel was studied in the present work. The result showed that at low austenitizing temperature (910°C - 1000°C), the mixed microstructures containing 12-28% volume fraction of lower bainite showed higher yield and tensile Effect of long-term service exposure on microstructure and The influence of prolonged service exposure on the microstructure and mechanical properties of a 1Cr-1Mo-0.25V steam turbine rotor steel has been studied. The samples for this study were taken from four locations of a rotor which had operated for 23 years. The operating temperatures at these locations were 288 °C, 425 °C, 510 °C, and 527 °C. The impact of retempering at 677 °C of steel
properties. The microstructure of creep resistant CrMo, CrMoV steel grades in the initial state with the common heat treatment of the used products (normalizing annealing followed by tempering) is not really the equilibrium state of the steel. Any thermal or mechanical influences are changing the microstructure in Microstructural and Mechanical Evaluation of a Cr-Mo-V In this work, the microstructure and mechanical properties of Cr-Mo-V cold work tool steel after additive manufacturing by the electron beam melting (EBM) process were evaluated. Based on the results obtained, the following conclusions can be drawn:
