Contribution of Nb addition to ductility and corrosion resistance of 06Cr13 stainless steel after dual-phase annealing and in-situ tensile study on deformation-fracture mechanisms

Key Points

• Ductility and corrosion resistance improve significantly with Nb addition, enhancing performance under stress.
• Key metrics show a 20% increase in ductility and a notable reduction in corrosion rates after processing.
• Analysis of fracture mechanisms reveals that Nb addition influences deformation behavior during testing.
• These findings suggest that optimizing Nb levels could significantly enhance the usability of stainless steel in various environments.
