The Application of the Extended Jiles-Atherton Model for Simulating the Magnetic Characteristics of X30CR13 Steel

Abstract

abstractEN: The application of magnetic-property oriented methods for non-destructive testing is verypromising due to its low cost and robustness. This paper presents the methodology of simulating themagnetic properties of martensitic X30Cr13 steel applying the extended Jiles-Atherton model. Onthe basis of experimental measurements, the parameters of the Jiles-Atherton model weredetermined by an evolutionary strategy together with gradient optimisation. A very good agreementbetween experimental hysteresis loops and the model was confirmed by a high value ofdetermination coefficient. The presented results open new possibilities of developing methods fornon-destructive testing of energetic turbines made of X30Cr13 stainless steel. Moreover,quantitative simulation gives a possibility of a better understanding of magnetisation processes.score: 5collation: 725-73
