%X The microstructure changes of pearlitic eutectoid steel induced by cold rolling were investigated by using SEM, TEM and XRD etc. According to the morphological characteristics of cementite lamellae, the deformed pearlite can be divided into three kinds: irregularly bent lamella (pearlite lamella originally inclined with large angles to the rolling plane and irregularly bent after deformation); coarse lamellae with shear-band (the rhomboidal blocks of weakly deformed lamella bounded by shear band) and fine lamella (heavily deformed lamella aligned parallel to the rolling direction with fine interlamellar spacing). As the rolling reduction increases, the proportion of fine lamella increases. Heavy cold rolling also induced the severe plastic deformation and dissolution of cementite.
