Abstract The hot compression deformation behavior of the spray-formed M4 high speed steel was investigated on thermal simulator at the temperature of 950 ℃-1150 ℃, strain rate of 0.01 s-1-10 s-1 and total strain of 0.7. The hot deformation constitutive equation for this alloy was obtained as well as the hot deformation activation energy. And the microstructures of the as-deposited alloy at different states were characterized presently. It is shown that the microstructure of the as-deposited M4 high speed steel possesses much finer and uniform-distributed grains without macrosegregation than the as-cast M4 high speed steel. The dynamic recrystallization are prominently performed during the deformation and the flow stresses are greatly affected by the temperature and strain rate. The morphology and distribution of the carbides are obviously influenced by the deformation temperature.
