Abstract Scope |
A pearlitic steels was microstructural, mechanical and thermally characterized after been proccesed by severe plastic deformation (SPD). Is well know that these techniques introduces a high level of deformation, leading to a high density of crystalline defects, and high pressure torsion is one of the most efective methods. These deformation conditions can modify the characteristics of both, the microstructure behavior and the mechanical properties. To investigate the potential modification of phases after severe plastic deformation, selected samples were characterized by differential scanning calorimetry (DSC) and were identified variations in the thermal stability and trasformation temperatures during heating. To analyze the mechanical properties, microhardness and nanoindentation tests were performed. The microstructure was examined using optical microscopy and electron microscopy. These results were compared with the properties of the steel before SPD. |
