The acting factors of influencing intragranular ferrite nucleation in non quenched and tempered medium carbon steel were investigated.By means of metallographic microscope and scanning electron microscope,the nucleation and growth of intragranular ferrite were investigated from three aspects of the size,distribution and type of inclusions.It provides a basis for smelting high quality clean steel.Experimental results show that when the composition of inclusions are Al2O3,TiN,VN etc.the best size of induced equiaxed ferrite is 2~4 μm; distribution of equiaxed ferrite coated inclusion is most conducive to the growth of ferrite;MnS precipitation on the surface of TiN is very benefit to induce intragranular ferrite.
