多层氧化膜应力腐蚀开裂裂尖的微观力学特性
Micromechanical Characteristics of SCC Crack Tip in Multilayer Oxide Film
摘 要
以氧化膜破裂理论和光电化学法的研究结论为基础，利用有限元分析方法对高温水环境中316不锈钢表面多层氧化膜应力腐蚀开裂（SCC）裂纹尖端微观力学状态进行了分析。结果表明：裂纹尖端区域的高应力应变区主要集中在氧化膜的Fe3O4层中；多层氧化膜中不同材料层的交界处均出现应力应变的突变；多层氧化膜中Cr2O3层和镍富集层的高应力是促使氧化膜强度减小并发生脆断的主要原因之一。

Abstract
Based on oxide film rupture model and photoelectric chemical method conclusion,the micromechanical state of the stress corrosion cracking (SCC) crack tip in the multilayer oxide film on surface of 316 stainless steel was analyzed by finite element method in high temperature water environment.The results show that the high stress-strain field at crack tip mainly concentrated in Fe3O4 layer of oxide film.There was a stress-strain mutation at the boundary of different material layers in multilayer oxide film.High stress in the Cr2O3 layer and the nickel rich layer was one of the main reasons for decreasing the strength of oxide film and brittle fracture.
