Compression dilatometer tests were used to study the hot deformation response of a zirconium (Zr)-2.5% niobium (Nb) alloy over the temperature range 650°C to 850°C and strain rates of 10−2.5 s−1 to 10+1 s−1. A high number of test conditions w

A direct comparison between the microstructural evolution during the annealing of a TEM thin foil (thickness ~100 nm) and the bulk material of Zr-2.5Nb-0.5Cu alloy is presented. The results indicate that at an intermediate temperature, (550 °C), dif

The effects of curvature on K, J, plastic zone, near-tip stress and fracture initiation in curved compact tension (CCT) specimens of unhydrided and hydrided irradiated Zr-2.5Nb materials are determined by three-dimensional finite element analyses. Ba

Duplex microstructure in Zr-Nb alloy possesses excellent mechanical properties. However, the effect of annealing temperature on the formation of duplex microstructure and its mechanical properties is not known. Determination of this effect is importa

Twinning in coarse-grained Zr is ubiquitous but not in nanostructured Zr due to the strong nano-confinement. Here we show that hexagonal close-packed (hcp) twins can proliferate in a nanolayered Zr-Nb as a result of the introduction of ductile body c

The precipitation of hydrides normal to the transverse direction in Zr-2.5%Nb pressure tube alloy when cooled under stress above a threshold value, is known as stress reorientation of hydrides. The ex-situ threshold stress values reported in the lite

Plastic deformation induced pyramidal ⟨c + a⟩ dislocations in a Zr-2.5Nb alloy have been investigated by electron tomography in the transmission electron microscope. The 10 1 − 1 1st order pyramidal planes were determined to be the primary slip
