Open publisher page 3 citations

Abstract

The effect of controlled forging and cooling process on structure of 38MnVS5 microalloyed steel was studied by a Gleeble 1500 hot simulator.The effects of process parameters,including amount of deformation,deformation temperature and cooling rate after forging,on microstructure of the steel were tested.The results show that the finest austenite grain can be obtained with 70% deformation and finish forging temperature of 850℃.The ferrite volume reduces and the ferrite grains become smaller with the increase of cooling rate after forging.
