Modeling Ultimate Tensile Strength and Phase Stability of Nickel-based Superalloys Different Generations
Authors: , ,
Abstract: Information about changes in the heat resistance and phase stability of Nickel-based superalloys is important for determining the service life of gas turbine engines. A model of the change in the ultimate tensile strength was obtained using machine learning and an analytical expression was proposed that allows determining the phase stability parameter of Nickel-based superalloys. Approximation and extrapolation of the ultimate tensile strength dependences were performed using the Larson-Miller temperature-time dependence. The adequacy of the obtained model is confirmed by satisfactory convergence of experimental and calculated results
