| Abstract: | The influence of austempering after prenitriding and nitrogen diffusion for Cr7Mo3V2Si andCr12MoV and the influence of quenching delay after prenitriding and nitrogen diffusion for 60Si2Mn on microstructuredistribution and microhardness gradient curues of these steels have studied. The results show that the service life ofcold dies made of steel Cr7Mo3V2Si and steel Cr12MoV after composite strengthening and toughening heat treatmentAPND and made of steel 60Si2Mn after composite strengthening and toughening heat treatment QDPND is obviouslyincreased. |
