Creep damage analysis of simulated-HAZ notched bar specimens of modified 9Cr-1Mo steel
Mechanical Engineering Journal, 2017 From the standpoint of evaluating Type IV creep damage in the fine-grained heat affected zones (FGHAZ) of welded joints, an analysis method combining continuum damage mechanics (CDM) and a cavity nucleation model is proposed and applied to the creep ...

Creep Deformation and Rupture Behaviour of P92 Steel at 923K
, 2013 Creep deformation and rupture behaviour of P92 steel has been examined at 923K for stresses ranging from 75 to 150MPa. The steel exhibited well defined primary, secondary characterized by minimum creep rate and prolonged tertiary creep stages. The stress

Rupture life of materials obeying exponential and power law creep.
Transactions of the Iron and Steel Institute of Japan, 1986 Based on the void growth and damage mechanics, the rupture time tr is derived as a function of the creep exponent n and the reference stress σo and the corresponding time to, for materials obeying exponential and power law creep. The analysis is extended to obtain parameters for prediction of long time behaviour. For materials which obey a simple power

Prediction of Long-Term Creep Rupture Life of Grade 122 Steel by Multiregion Analysis
, 2020 Conventional time-temperature-parameter (TTP) methods often overestimate long-term rupture life of creep strength enhanced ferritic steels. Decrease in activation energy Q for rupture life in long-term creep is the cause of the overestimation, since the ...

Creep damage is a time-dependent deformation in metals under a constant stress at high temperature condition. Since the 1980s, high chromium alloy steel P91 (9%Cr-1%Mo-0.25%V) is highly demanded in high temperature industries (Saha, 2003).
