High temperature compression test is carried out on the 10CrNi8MoV steel by using Gleeble-3500 thermo-mechanical simulator. The flow stresses of the 10CrNi8MoV steel under different temperatures, strain rates and strains are obtained, and its hot process map is established. The results indicate that the 10CrNi8MoV steel has two suitable hot deformation regions, which are the medium/high temperature and medium/low strain rate (1 020-1 100 ℃ deformation temperature and 0.001-0.1 s-1 strain rate) region, and the high temperature and high strain rate (1 150-1 200 ℃ deformation temperature and 3-10 s-1 strain rate) region. When the 10CrNi8MoV steel deforms in the above two regions, the microstructure is uniform and fine dynamically recrystallized grains are fine.
