Modeling the room temperature deformation of a two-phase zirconium alloy
TL;DR: In this paper, a new modeling approach, which combines the finite element method (FEM) and elasto-plastic self-consistent model (EPSC), was used to model the deformation behavior of hot-rolled Zr-2.5Nb plate material and was shown to be an effective method for describing the multiphase materials.

Anisotropy of yielding in a Zr-2.5Nb pressure tube material
TL;DR: In this article, the anisotropy of a Zr-2.5Nb pressure tube was determined experimentally by testing samples in uniaxial tension and in shear, by testing in torsion “mini” pressure tubes from the same material.

Analysis of steady-state thermal creep of Zr-2.5Nb pressure tube material
TL;DR: In this article, the steady-state thermal creep rate in the axial and transverse directions of Zr-2.5Nb of pressure tubes, used in CANDU nuclear reactors, was determined.

Flow behaviour of a modified Zr-2.5wt%Nb pressure tube alloy
TL;DR: In this paper, anisotropy in flow behavior of cold worked and stress-relieved Zr-2.5wt%Nb pressure tube alloy was characterized by performing tensile tests in the temperature range of 298 −823 K and under a constant nominal strain-rate of ∼3 −10 −4 ǫ s −1.

Experimental investigation of sagging of a completely voided pressure tube of Indian PHWR under heatup condition
TL;DR: In this article, an experimental set-up has been designed and fabricated to simulate sagging (downward deformation) of pressure tube due to its own weight and the weight of fuel bundles for 220 MWe IPHWRs.

Tracer diffusion in α-Zr
G.M Hood,R.J Schultz +1 more
TL;DR: In this paper, the authors measured tracer diffusion in α-Zr single crystals at temperatures close to 840°C and showed that there is an overall tendency for the solute diffusion coefficient to increase as the atomic radius and the valence of the solutes decreases.
