RISEvaluation of Creep Strength Reduction Factors for Welded Joints of Grade 122 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: HCM12A (ASME Grade 122) is used for boiler components in thermal power plants because of its high creep strength. However, a type IV creep damage formed in the heat-affected zone can cause ...
Evaluation of Creep Strength Reduction Factors for Welded Joints of Modified 9Cr-1Mo Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Creep strength of welded joint for high Cr ferritic heat resisting steels decreases due to Type-IV failure in heat-affected zone (HAZ) during long-term use at high temperatures. In order to ...
Evaluation of Microstructures and Creep Damages in the HAZ of P91 Steel Weldment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The creep strength of welded joints in high Cr steels decreases due to the formation of Type IV creep damage in heat-affected zones (HAZs) during long-term use at high temperatures. This paper ...
Characterization of Structural Embrittlement of Creep Crack Growth for W-Added 12%Cr Ferritic Heat-Resistant Steel Related to the Multiaxial Stress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In components under static creep loading condition, the multiaxial stress fields appear due to the plastic constraint and they produce a more brittle type cracking behavior. From a practical ...
Evaluation of Creep Crack Growth Rate of P92 Welds Using Fracture Mechanics Parameters
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High Cr ferritic heat resisting steels have been widely used for boiler components in ultrasupercritical thermal power plants operated at about 600°C. In the welded joint of these steels, ...
