What material properties does incoloy800h have?
Combined with the creep characteristic quantity-temperature parameter model, this study conducted an in-depth study on the creep behavior of Incoloy800H pipes at 600-1050°C. Through experimental data fitting, we derived the reliability equation of the material's steady-state creep rate, creep rupture time, and the start time of the third stage of creep. On this basis, we further established a model of the relationship between pipe allowable stress, service temperature and reliability.
Experimental results show that the determined creep characteristic quantity reliability equation can better predict the change behavior of the creep rate, creep rupture time and the start time of the third stage of creep of Incoloy800H pipes at different temperatures. The long-term creep data are all located within the prediction area of the corresponding creep equation under the condition of reliability 0.997, which shows that our model has high prediction accuracy and reliability.
Compared with the allowable stress values recommended by ASME, the allowable stress evaluation results based on the creep characteristic quantity reliability equation are more accurate. This provides important theoretical basis and technical support for the safe use of Incoloy800H pipes in high temperature environments.
In future research, we will further optimize experimental conditions and data analysis methods to improve the prediction accuracy and applicability of the model. At the same time, we will also pay attention to the creep behavior of other types of alloy materials at high temperatures, in order to provide more comprehensive and reliable guidance for various engineering applications.
In short, this study combined the creep characteristic quantity-temperature parameter model to conduct an in-depth discussion of the creep behavior of Incoloy800H pipes at high temperatures and established a corresponding mathematical model. These results have important theoretical significance and practical value for predicting the performance changes of alloy materials in high temperature environments, and will help promote technological progress and application development in related fields.
