Deformation Behavior of Finely-Lamellar Pearlite During Multiple Cold Plastic Deformation of Eutectoid Steel

Аннотация

Deformation behavior of finely-lamellar pearlite in steel with 0.78% C during multiple cold plastic deformation by drawing is considered. It is revealed that during deformation apart from ferrite platelet thinning with an increase in overall reduction cementite phase behavior starts to play a more important role. The change in distance between pearlite platelets in relation to the degree of deformation is evaluated. The connection between microstructure transformation and changes in mechanical properties during drawing is established.
