Abstract Scope Nanostructured steels have recently gained attention due to the roles of grain boundaries (GBs) in enhancing mechanical strength and absorbing irradiation induced defects. In order to produce bulk nanostructured steels, severe plastic deformation (SPD) techniques such as equal-channel angular pressing (ECAP) and high-pressure torsion (HPT) have been developed as effective grain refinement techniques. One concern for nanostructured materials, however, is their thermal stability as the stored strain energy and GB energy can act as driving forces for recrystallization and grain growth. In this study, ECAP and HPT processed Kanthal-D (FeCrAl, ferritic) and 304SS (FeCrNi, austenitic) were annealed at temperatures ranging from 500-700 oC. Microhardness was used to determine temperatures at which these steels become thermally unstable. Electron backscatter diffraction (EBSD), X-ray diffraction (XRD), and transmission electron microscopy (TEM) were used to determine microstructures after annealing. In both ECAP processed steels recrystallization occurs, while the HPT processed steels show grain growth.
