Abstract
Super alloys present a real challenge to near-net shape rolling because of their high strength at elevated temperature, limited ductility, and narrow forming temperature range. Currently, the simulation of shape rolling requires application of time-consuming 3D finite element techniques. It is necessary to know the most important characteristics of the material behavior during processing in a small fraction of time taken by a finite element analysis in order to reduce the design and analysis cycle time. The upper bound elemental technique (UBET) is a rapid load estimating technique that has the potential to produce the results in a short time. Therefore, this paper presents an UBET-based simulation tool for modeling shape rolling of high-temperature aerospace materials. Simulation results have been compared with industrial data obtained for high-temperature alloys such as IN718 and TI-6AL-4V.
