Abstract
The engineering simulation software Deform 3D is applied for development and adoption of 3D simulation of manufacturing of pressed semifinished 1600 mm blades. Three stages of pressing are considered, including heating, intermediate cooling in transporting, and cooling of billet as a consequence of heat exchange with the die. On the basis of simulation, the distribution of temperature fields and strain fields is obtained at various stages of pressing. The calculation reveals that, at all pressing stages, the temperature of billet does not exceed the temperature of polymorphic transformation. The simulation demonstrates that such billet can be pressed in accordance with standard specifications.
