(1)蒸汽发生器传热管的应力腐蚀破裂(SCC)采用慢应变速率应力腐蚀实验(SSRT)方法研究了国内外压水堆蒸汽发生器(PWR SG)使用的管材Incoloy-800,Inconel-600,Inconel-690,以及少量使用的321SS在高温(260℃)含氧含氯化物水中的SCC行为,指出In-690具
(1) Stress corrosion cracking (SCC) of heat transfer tube of steam generator The tube Incoloy-800 and Inconel-800 used in pressurized water reactor steam generator (PWR SG) at home and abroad were studied by slow strain rate stress corrosion test (SSRT) 600, Inconel-690, and the small amount of 321SS used in high temperature (260 ° C) oxygenated chloride containing water indicate that In-690
