AbstractThe microstructures, true stress-true strain curves and micro-hardness of two stainless steels, containing 1.0%N(N10) and 316L, after compressive deformation were measured. It was found that the mechanical twinning and sliping participated together in the deformation for the two steels under the deformation less than 20%, but sliping turned to be dominant for 316L when the deformation was increased to 50%, the high nitrogen steel N10 still remained the above two mechanisms. There was no alpha' martensite transformation in the steel N10 under deformation, showing better structure stability, but martensite appeared in the 316L. The strength, microhardness and work-hardening effect of the steel N10 were much higher than those of the 316L, while the strengths could be largely enhanced by cold deformation for the two steels. The microhardness was related to the grain orientation for the two steels and the effect of grain orientation was larger than that of the microstructure inhomogeneity. The reason why the high nitrogen stainless steel has the excellent property was also discussed.
