A method for forging a thermomechanical part and including: providing a billet produced in a titanium alloy having a beta transus temperature; carrying out at least one operation of forging a blank of the billet at a temperature T1 lower than the beta transus temperature Tb from before carrying out the forging operation whereby a blank is completed; carrying out a final forging the blank at a temperature T2 greater than the beta transus temperature Tb from before carrying out the forging operation whereby a blank is completed. The forging operation from the blank-forging carries out, on every point of the billet, a deformation greater than a minimum deformation rate. The method can be used for a rotating part of a turbine engine.
