The mechanical properties of negative poisson ratio(NPR)steel are studied and compared with those of naval 921A steel.The results show that NPR steel has high tensile strength while maintaining excellent toughness,and its ability to absorb energy in plane direction is strong.Under the condition of high strain rate,the yield strength and ultimate strength of NPR steel are greatly improved,showing a strong strain rate sensitivity.At the same time,the corrosion resistance,the cold bending workability and low/non-magnetic properties of NPR steel are excellent.The research show that NPR steel has good comprehensive properties,especially suitable for large deformation,high stress and high ductility of the engineering scene,and it is expected to be used in the field of anti-explosion and anti-shock for naval ships.
