Establishment of Strain Compensation High-Temperature Rheological Stress Model for GH4706 Superalloy Based on the Arrhenius Equation
The high-temperature rheological stress model of GH4706 superalloy plays a crucial role in guiding the production of GH4706 forgings and predicting equipment tonnage.In this paper,a superalloy strain compensation high-temperature rheological stress model based on the Arrhenius equation is established and the related process is summarized,so that the process is successfully automated and necessary mathematical tools are modularized.Therefore,a Python comprehensive data processing and analysis module is established,which is composed of six modules and can automatically realize the data processing and analysis operations such as the introduction of high temperature rheological stress curves,data processing,automatic fitting of material parameters,and evaluation of fitting accuracy,etc.Finally,the high temperature rheological stress model of GH4706 superalloy is established using this module,the root mean square error(RMSE)is only 8.316,and the calculation speed is very fast,which has great significance for accelerating the production efficiency.
