) 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.
