atom probe ATR Fugen cast austenite stainless steel (CASS) Charpy impact test prediction model recirculation pump casing thermal aging embrittlement
Thermal embrittlement of cast austenitic stainless steel components from the decommissioned advanced thermal prototype reactor Fugen has been characterized. Cast stainless steel materials were obtained from recirculation pump casing. The actual time at temperature for the materials was 138,000 h at 275 oC. The “Fugen” material show modest decrease in Charpy-impact properties and a small increase in micro-Vickers hardness in ferrite phase because of thermal aging at relatively low service temperatures. ...
