Delayed hydride crack growth of Zr-2.5wt% Nb pressure tube
- 1. KAERI, Taejon (Korea, Republic of)
Description
The effect of specimen direction on the delayed hydride crack(DHC) growth was analyzed with the specimens of Zr-2.5wt% Nb alloy which has been used for the pressure tubes in CANDU nuclear reactors. The specimen of circumferential notch direction showed more DHC resistance than that of longitudinal notch direction did. The fracture surface of the circumferential specimen showed severe roughness because of secondary cracking of original cirsumferential hydride platelets. The striation marks were observed and the formation of them was reviewed
