The flow behavior, mechanical and physical properties of alloy Fe-29 Ni-17 Co were studied using hot compression and hot rolling tests over the temperature range of 900 °C to1 200 °C and strain rates of 0.001 s −1  to 1 s −1 . At temperatures below 1 100 °C, the flow curves were similar to those of dynamic recovery; whereas, at higher temperatures, faint peaks appeared on the flow curves. A modified power-law constitutive equation was used to model the dependences of flow stress on temperature and strain rate in different deformation regimes. The Kocks–Mecking equation was used to model the flow curves and to measure the mean flow stress of the material in hot rolling. The samples hot rolled at 1 100 – 1 200 °C to a reduction of 30 – 40 % showed the best combination of ductility and strength and low thermal expansion coefficient. Microstructures of the hot rolled samples indicated that hot rolling at 1 100 – 1 200 °C to reduction of 30 – 40 % leads to complete dynamic recrystallization.
