SECTION II ASME Boiler and Pressure Vessel Code An International Code. Combined crystal plasticity and grain boundary modeling of Aug 20, 2019 · Part 1 of this work described calibrating a CPFEM model for the creep and creep-rupture of Grade 91 steel to long-term creep test data collected at 600 °C by Kimura et al . The only consistent data using the same batch of Grade 91 material available to validate this model is an additional creep test at 600 °C and 150 MPa.
Sep 01, 2019 · Ray et al. [6,7] have investigated the creep behavior of service exposed 2.25Cr1Mo steel between 773 and 873 K. Samples are machined from tubes which have been exposed for 17 years at 813 K and 40 MPa in a 120 MW thermal power plant superheater and reheater boiler tubes. They have predicted that the tubing could easily withstand another 100,000 Influence of Oxidation on Estimation of Long-Term Creep Aug 02, 2019 · The influence of oxidation on the estimation of long-term creep rupture strength is investigated for 2.25% chromium (Cr)1% molybdenum (Mo) steel specified as JIS STBA 24, JIS SCMV 4 NT, and ASTM A542/A542M by the LarsonMiller method using creep rupture data in the National Institute for Materials Science (NIMS) Creep Data Sheets at 450650 °C for up to 313,000 h. Material characterization, constitutive modeling and Jan 08, 2015 · The JohnsonCook and Arrhenius models were used to characterize the uniaxial tension and the stress relaxation behavior, respectively. Finite element model of hot stretch bending was created according to the laboratorial experiment setup in ABAQUS based on
Oct 29, 2010 · The material under investigation was G17CrMoV5-10 cast steel taken out (in the form of a section) from an internal frame of steam turbine serviced for about 250,000 h. Performed research has proven that through the microstructure degradation long-term service contributes to an embrittlement and decrease in yield strength and tensile strength. Orientation dependent behavior of tensile-creep Jun 10, 2021 · The good reproducibility of the creep tests proves the anisotropic behavior, as summarized in Table 2. The endurance time of Creep-T specimens can reach to 172.6174.5 h, while the Creep-R specimens keep at the range of 55.665.1 h. The DR Elongation and DR Endurance time are as high as 112.0 % and 65.2 %, respectively. Physical Metallurgy of Modern Creep-Resistant Steel for Nov 30, 2016 · This study seems to show that at 650°C no effect in creep strength is seen by increasing Ni content of 15Cr1Mo steel but there was huge creep strength improvement in comparison with T92 creep steel, whose composition is given as 9Cr-0.5Mo-1.8W-V-Nb, at each temperature.
