Because of the complicated shape, the slight profile dimension and the bad formability of superalloy, defects such as folds, cracks and surface damages are usually existed during precision forging process. Thermal parameters compromised of stress field, strain field and temperature field could be obtained using Deform software, the trial production time can be shortened exactly by optimized FEA results. It has been found that Deform could guide the precision forging design and actual production process for airfoils.
