The effects of hydride morphology on the axial fracture toughness of cold-worked Zr-2.5Nb pressure tube material have been determined between room temperature and 240°C. Tests were performed on small compact tension specimens machined from samples o

Delayed hydride crack velocities in Zr-2.5 wt% Nb alloys with different thermomechanical treatments were measured. Materials with higher strength have higher crack velocity, and the stepwise crack propagation occurred by smaller increments associated
