中文摘要
快中子增殖反应堆的运行温度为550 ℃,因此从结构完整性的角度出发,对堆芯蠕变疲劳强度进行评估是必不可少的。具有圆孔的结构可见于例如支撑圆板或管板中。在含圆孔板中,裂纹在孔边萌生,因此对此类结构的蠕变疲劳强度进行准确评估是必要的。加工了由SUS 304不锈钢制成的带有一个圆孔的板,并在550 ℃下进行疲劳和蠕变疲劳试验以观察萌生和扩展。
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.
