Abstract

X-ray diffraction detailed analysis of nitrogen-added austenitic 316LN stainless steels with different nitrogen concentrations (0.07, 0.11, 0.14, 0.22 wt.%) was carried out in creep-tested (at 923 K, 200 MPa) and solution-annealed conditions. The effect of nitrogen on lattice parameter was studied before and after creep testing. Size and strain were estimated through Williamson–Hall analysis. High nitrogen-added 316LNSS showed lower dislocation density. Increase in creep rupture lifetime with nitrogen content correlated well with the lattice parameter, crystallite size, and strain.

蠕变变形加氮 316LN 不锈钢的 X 射线衍射分析

在蠕变试验（923 K，200 MPa）和固溶退火条件下，对不同氮浓度（0.07、0.11、0.14、0.22 wt.%）的加氮奥氏体 316LN 不锈钢进行了 X 射线衍射详细分析。在蠕变试验前后研究了氮对晶格参数的影响。通过威廉森-霍尔分析法估算了尺寸和应变。高氮添加的 316LNSS 显示出较低的位错密度。蠕变断裂寿命随氮含量的增加而增加，这与晶格参数、晶粒尺寸和应变密切相关。
