The increasing thrust-weight ratio of aero-engines puts forward more stringent requirements for the high-temperature service performance of turbine disk alloys. The alloying degree and γ′ phase content of nickel-based wrought superalloys used in turbine disks with a service temperature of higher than 700 ℃ are extremely high, which significantly increases the deformation resistance, reduces the thermoplasticity and narrows the hot working window. Hence,cracking and structural instability are easy to occur during the hot deformation. This paper has introduced the hot working process of such hard-to-deform superalloys, corrections of friction and adiabatic heating effect, and construction methods of the constitutive model and processing map. Besides, the research progress on hot deformation behaviors of the typical hard-todeform superalloys, including Rene65, U720Li, ЭК151, ЭЛ975 and TMW has been reviewed. The future research direction of such alloys has been prospected, which can provide certain reference for optimization of the hot working process.
