Summary:The invention discloses a method for optimizing parameters of a GH696 alloy forging technology. The method for optimizing the parameters of the GH696 alloy forging technology is used for solving the technical problem that the range of optimizing the parameters of the GH696 alloy forging technology with an existing method is narrow. According to the technical scheme, the value eta of the energy dissipation rate and the plastic flow instability parameter (please see it in the specifications) are calculated based on flow stress and stress data which are obtained through a thermal simulation compression test; an energy dissipation rate curve graph and a plastic flow instability parameter curve graph are established and stacked for constructing a hot working graph, the maximum energy dissipation rate eta1 and the maximum energy dissipation rate eta2 corresponding to the area with the plastic flow instability parameter smaller than or equal to 0 are determined, and the parameters of the GH696 alloy forging technolo
