Summary:Title screen
In this paper, the mechanical properties and fracture mechanisms of the high-nitrogen austenitic steel Fe-17Cr-10Mn-7Ni-0.95V-0.8N-0.1C (in wt %) processed by different thermomechanical treatments are investigated. Cold rolling and short-time solid solution hardening contribute to the formation of a rather homogeneous fine-grained structures in the steel, which possess high strength, sufficient plasticity and exhibit excellent product of strength and elongation ([sigma][YS]=540-570 MPa, [sigma][UTS]=900-950 MPa, EL=37%, PSE=33-35 GPa %) in comparison with coldrolled specimens possessing high strength properties, but extremely low elongation ([sigma][YS]=1200 MPa, [sigma][UTS]=1650 MPa, EL=1%, PSE=7 GPa %).
