| Abstract: | In order to optimize the hot punching process of automobile axle housing，the continuous cooling transformation processes of the FSN 400 steel under static and dynamic states were studied by using Gleeble-2000 thermal simulation machine，and the effects of deformation temperature and cooling rate on microstructure of the steels were nalyzed.The results show that the axle housing is preferably hot punched at 850 ℃ and then cooled at rate 5 ℃·s~(-1)，and its microstructures are ferrite，pearlite and small amounts of granular bainite. |
