The microstructure evolution during deformation enhanced transformation of under cooled austenite of a plain low carbon steel has been investigated by means of hot compression simulation experiment under various conditions of strain rate,deforma- tion temperature and strain. The effect of austenite grain size on the strain enhanced ferrite transformation has been studied. The ferrite dynamic recrystallization involved in successive hot deformation has been explored.
