Forged turbine discs manufactured from high temperature resistant nickel base super alloys are classified as security related components in aero engine applications. This classification results in high demands and standards regarding the quality assurance during forging processes. A widespread tool to support the quality assurance are forging simulations. To meet this quality requirements it is necessary to prepare exact guidelines for external suppliers. An extensive literature study has been made to show the requirements that materials, components and manufacturing processes are exposed to, when it comes to aero engine applications. A state of the art analysis was proceeded to present forging simulations and the different displays as well as the modelling behind it. With re spect to the validation of microstructure simulations an exemplary investigation has been conducted to show the limitations of forging simulations. At the end this thesis provides strategic recommendations for MTU Aero Engines AG, how to integrate forging simulations into the existing quality assurance concept. The basis for this optimization has been done by the quality function deployment method.
