Description
  • Using the high pressure torsion (HPT) at increased temperature the medium carbon steel (AISI 1045) was an experimental material to conduct deformation process.. The influence of deformation processing parameters was evaluated by microstructure analysis and mechanical properties. The strengthening was assessed by microhardness measurements across the disc, by tensile tests and by in-situ measured torque. The hardness measured at disc edge was gradually increasing as straining increases. The SEM and TEM investigations were carried out to analyze the microstructure evolution regarding the strain introduced. TEM investigation confirmed the increasing misorientation of grains, the fragmentation and dissolution of the cementite lamellae. An indistinctive deformation of ferrite at centre of disc and preserved cementite lamellae morphology.
