Abstract: Test gear steel Cr14-Co13-Mo5-Ni2 is melted by 5 t VIM + 1 t VAR double-vacuum melting process. The effect of deformation temperature (1040-1080 ℃ ),amount of deformation (20%-60% ) and deformation rate (1-20 s-1) on grain distribution and grain size of Cr14-Co13-Mo5-Ni2 steel has been tested and studied by using Gleeble-1500 thermal simulation machine. Results show that with deformation temperature 1040 °C , amount deformation 60% and deformation rate 20 s-1 , the Cr14-Co13-Mo5-Ni2 gear steel has fine, round and homogeneous grain structure, and its average grain size is 4.03 μm.
