Discrepancies remain about nature of dislocation-interstitial interaction governing yielding discontinuity in fcc materials. Here, we show that outward diffusion of nitrogen from stacking fault (SF) into matrix causes strain redistribution, leading to lowering stacking fault energy. Local fluctuation of nitrogen promotes fault growth coupled with nitrogen-enriched zone, contributing to enhanced plasticity.

奥氏体钢中氮诱导的屈服点现象

关于位错-间隙相互作用的性质控制fcc材料中产生不连续性的差异仍然存在。在这里，我们表明氮从堆垛层错（SF）向外扩散到基质中会引起应变重新分布，从而降低堆垛层错能量。氮的局部波动促进断层的生长以及富氮区，从而增强了可塑性。
