摘要
利用电子显微镜和成分分析技术研究了 YUS70 1奥氏体不锈钢 ROF内罩在高温使用前后的显微组织变化特征、冲击断口形态及其对应位置的扫描金相显微组织和化学成分特点 ,提出了YUS70
Studied in this paper were the TEM microtexture characteristics,the chemical composition chatacteristics,the impact fracture shape and the corresponding SEM microtexture of the YUS701 austenitic stainless steel ROF internal cover appearing under high temperature before and after it came into service by means of electronic microscopy and chemical composition analysis.The brittleness mechanism of the YUS701 austenitic stainless steel usually worked over a long period of time under super high temperature in the medium of hydrogen and oxygen was put porward.
