以蠕变后的优化高氧含量FGH96合金为研究对象,采用SEM对断口附近的组织进行观察,分析蠕变孔洞形核位置。结合EBSD分析蠕变孔洞形核与晶粒之间的关系。
Taking the optimized high-oxygen content FGH96 alloy after creep as the research object, the microstructure near the fracture surface was observed by SEM, and the nucleation position of creep holes was analyzed. Analyze the relationship between creep pore nucleation and grains in combination with EBSD.
