Abstract

Mechanical properties of components made from nickel based superalloys rely on the microstructure that forms during their thermomechanical processing. The ability for predicting and controlling microstructure during the processing is of the utmost importance for this class of alloys. In this work, the applicability of JMAK-type (Johnson-Mehl-Avrami-Kolmogorov) models is studied in the context of industrial manufacturing processes. The results of FEA (finite element analysis) based predictions of microstructure evolution in ATI 718Plus® alloy during the hot deformation process are presented. The limitations of the JMAK-type approach are discussed in the paper and concepts for an alternative modelling approach for microstructure prediction in nickel based superalloys are presented.
