| Description | Journal: Materials Research Express The effects of nitrogen on the nanomechanical property and localized plasticity of nitrogen alloyed 316 series austenitic steels were investigated by using nanoindentation. Slip steps around indentations have been imaged and have indicated that nitrogen increases slip planarity greatly. The load versus displacement curves show that the addition of nitrogen increases the first excursion load and the probability of occurrence of the second excursion, which is attributed to slip planarity caused by nitrogen and the local work softening on the operative slip plane. Additionally, nitrogen increases hardness and elastic modulus, while it promotes nanoindentation creep. Planar slip caused by nitrogen inhabits the formation of strain-induced α´ martensite and then promotes the creep deformation. |
