Microstructure and mechanical properties of UFG medium carbon steel processed by HPT at increased temperature.

Original language description

Using the high pressure torsion (HPT) method the medium carbon steel (AISI 1045) was an experimental material to conduct deformation process. The torsion experiment was performed at room and increased temperature. The influence of deformation processingparameters (?ef) was evaluated by microstructure analysis and mechanical properties. The strength behaviour was assessed by microhardness measurements, by tensile tests and by torque. The SEM and TEM investigations were applied to analyze the microstructure evolution across the disc in order to evaluate the effect of the strain effect. TEM investigation confirmed the presence of UFG structure, the fragmentation, alignment and dissolution of the cementite lamellae to the shear plane with increasing straining.
