摘要

Strengthening characteristics of 201 stainless steel under nitrogen enhancement from zero to approximately 1.5 wt percent N concentration are improved with increasing nitrogen. Yield and tensile strength, strain hardening, and cold-work/hardness relationships are proportional to nitrogen concentration. Strengths increased with increasing nitrogen up 1,0 wt percent, even though at nitrogen concentrations greater than ?.65 wt percent, Cr_2N precipitates formed. Strengthening models from tensile and cold working are discussed, compared, and correlated to nitrogen concentration, tensile properties, and micrestructure.
