Abstract
⺠The delayed hydride cracking (DHC) velocity of Zircaloy-2 was measured. ⺠The velocity followed the Arrhenius law up to 270 °C. Activation energy was 49 kJ/mol. ⺠The threshold stress intensity factor for the DHC was from 4 to 6 MPa m1/2. ⺠An increase in material strength accelerated the DHC. ⺠Precipitation and fracture of hydrides at a crack tip is responsible for the DHC.
