【Abstract】 Based on the dissipative structure theory, a method to determinate the thermomechanical parameters for forging of difficult-to-deformation materials was explored in this paper in order to maintain the consisteney in microstructure and properties. Two criteria were proposed for defining the stable regions of the thermomechanical parameters for forging and based on the criteria that of GH169 and TC11 alloys were graphically presented for the first time, leading to some conclusions valtlable for producing the critical forgings of these alloys. And finally, incorporating the proposed method into the deformation and heat transfer coupling analysis by using finite element method was suggested to control the quality of the difficult-to-deformation materials forgings.更多还原
