Over forty years of in-reactor testing and over thirty years of operating experience in power
reactors have provided a broad understanding of the in-reactor deformation of cold-worked …

Cold-worked Zr—2.5 wt% Nb pressure tubes for Canada Deuterium Uranium pressurized
heavy water reactors are made by hot extruding hollow billets into tubes that are cold …

Different techniques of the X-ray diffraction line profile analysis (XRDLPA) have been used
to study the microstructural parameters of the heavily deformed solid polycrystalline Zircaloy …

Zirconium alloys are susceptible to a stable cracking process called delayed hydride
cracking (DHC). DHC has two stages:(a) crack initiation that requires a minimum crack …

The recrystallization of a Zr–2Hf alloy sheet deformed by plane strain compression at room
temperature and then annealed at selected temperatures has been studied. The evolution of …

In this study, the mechanical properties in a Zr-Nb alloy plate with bimodal basal texture
microstructure have been evaluated by tensile, Vickers hardness and nano-indentation …

The anisotropy of yielding, as measured by the ratio of yield stress in the axial and
transverse directions of Zr-2.5 Nb pressure tubes used in Canada Deuterium Uranium …

The steady-state thermal creep rate in the axial and transverse directions of Zr-2.5 Nb of
pressure tubes, used in CANDU nuclear reactors, was determined. The data were obtained …

Abstract Changes in shape of internally pressurized tubes caused by operating
temperatures and pressures are enhanced by fast neutron irradiation. Lengths and …

Diffraction line profile analysis was done to characterize the change in the dislocation
density at different stages of the processing route of a Zr-2.5% Nb pressure tube. Two …
