Thermal compression deformation experiments on Ni-Cr-Fe heat-resistant alloy for advanced ultra-supercritical boilers were conducted using a Gleeble-3500 thermal simulator testing machine over a temperature range of 950 ℃–1 250 ℃, strain rates of 0.01 s⁻¹-10 s⁻¹, and a strain of 0.7. Based on the Arrhenius hyperbolic sine model, strain factor is innovatively introduced to construct an improved constitutive model suitable for heat-resistant alloys, and two indexes, correlation coefficient R and absolute error δ, are used to evaluate the accuracy of the model's prediction of rheological stress; At the same time, by constructing the hot processing map of the heat-resistant alloy and the microstructure analysis, the optimal range of hot working process parameters of the alloy is systematically evaluated and determined. The results showed that the optimal fitting order of the material constants and strain of the improved constitutive model with coupled strain was 6, the correlation coefficient R was 0.988 89, and the absolute error δ was 5.905%. The model had good predictive ability for the rheological stress of heat-resistant alloy; The activation energy Q for hot deformation was calculated as 389 kJ/mol. Based on microstructural analysis, the optimal hot working process for the Ni-Cr-Fe heat-resistant alloy was identified as 1 150 ℃-1 200 ℃ and 0.1 s⁻¹-1 s⁻¹.
