Effects of Nitrogen on Deformation Behavior of Duplex Stainless Steel
이상 스테인레스강의 변형거동에 미치는 질소의 영향
Abstract
The effects of nitrogen on the deformation behavior of duplex stainless steel have been studied The variation of strength was correlated with the characteristic microstructures. Analysis based on Hall-Petch relation confirmed that nitrogen enhances phase-boundary strengthening effect. The evolution of dislocation structure, slip traces, and misorientation distribution during deformation were also characterized to elucidate the effect of nitrogen on inelastic deformation mechanism.
