中文摘要
翻译
快增殖堆的工作温度为550℃,从结构完整性的角度考虑,蠕变疲劳强度的评估是必不可少的。例如,在支撑圆板或管板中可以看到具有圆孔的结构。在有圆形孔洞的板中,裂纹是从孔边开始的,因此对这类结构的蠕变疲劳强度进行准确的评估是必要的。加工了SUS 304不锈钢单孔板材,并在550℃下进行了疲劳和蠕变疲劳试验,观察了其萌生和扩展过程。
英文摘要
Operating temperature of fast breeder reactor is 550 degree Centigrade, so that the evaluation for creep-fatigue strength is indispensable from the viewpoint of structural integrity. The structures having circular holes are seen in ,for instance , supporting circular plate or tube sheet. In plate having circular holes, crack initiates at hole sides, so that the accurate evaluation of creep-fatigue strength is necessary in such structures. Plate made of SUS 304 stainless steel with one circular hole is machined, and fatigue and creep-fatigue tests were conducted at 550 degree centigrade to observe initiation and propagation.
