Annealing behavior of nano-crystalline austenitic SUS316L produced by HPT

Nano-crystalline (NC) 316L austenitic stainless steel sample was prepared by means of High Pressure Torsion (HPT) and post-deformation annealing. Uniaxial tensile tests at room temperature showed the nano-crystalline sample exhibits extreme high yield strength up to 2230 MPa, which is the highest ever reported in the literature.
