ANN approach for Larson-Miller factor approximation in the space of alloy features

Nickel-based superalloys are compositions with complex alloying and heterophasic structure. The use of the database on the chemical composition of the alloy and its heat resistance as ANN input parameters allowed to obtain a series of curves of the dependence of the change in heat resistance on the temperature-time conditions of the tests interpolated into the Larson-Miller parameter. The analysis of dependences allows us to distinguish the parameters of the initial heat resistance and thermal stability of alloys. The dependence of heat resistance and thermal stability from the content of the main strengthening elements are obtained by ANN simulations. The results of the computations coincide with the experimental data.
