Microstructure and Property of 20CrMo Steel with the ...

The microstructures and properties of 20CrMo steel in rare earth catalysis and conventional carburization have been investigated by using the homemade rare earth energizer. The results show that the diffusion rate of carbon increases due to rare earth catalysis, so the time of carburizing decreases by about 30 %, and the martensite microstructures are refined on the surface layer.
