Preform design to reduce forging load and grain size simultaneously in disk forging of IN718
Journal of Materials Research and TechnologyIn this study, we propose a new methodology for designing preform shapes for turbofan blisk and disk forgings of IN718 superalloy using a CNN (Convolutional Neural Network). The objective function of the preform design model is set to minimize grain size
