Zr-2.5Nb 압력관의 수화물에 의한 파괴인성 취화에 관한 연구
Fracture Toughness Embrittlement by Hydride in Zr-2.5Nb Pressure Tube
- 발행 : 2000.11.02
초록
Unpredictable failures can occur due to the DHC (delayed hydride cracking) or the degradation of fracture toughness by hydride embrittlement in CANDU pressure tube which can result from the absorption of hydrogen or deuterium in the high temperature coolant. To investigate the hydride embrittlement of CANDU Zr-2.5Nb pressure tube, the transverse tensile test and the fracture toughness test were performed from room temperature to
