Conclusions
-
1.
Use of the thermomechanical treatment of structural steels to a pearlitic structure (TMTp) in the production cycle for cold-rolled (cold-drawn) steel (following the scheme: TMTp→ cold deformation→ recrystallizing anneal) yields a microstructure with globular carbides which possesses increased ductility.
-
2.
Annealing by means of the heat introduced prior to rolling, and slow cooling from the final rolling temperature (780°C), also result in the formation of globular carbides, but with somewhat lower ductility than after TMTp.
-
3.
TMTp increases the resistance of structural steels in the quenched and tempered condition to fracture in impact bending.
