Anisotropy of mechanical properties of excel zirconium alloy. [Zr-3. 8%Sn-0. 8%Mo-0. 8%Nb]
- McGill Univ., Montreal (Canada)
The anisotropy of the plastic deformation of Excel alloy (Zr-3.8 wt.% Sn-0.8 wt.% Mo-0.8 wt.% Nb) was studied by means of constant true strain rate compression tests on specimens machined from a CANDU pressure tube. The specimens were oriented along the three principal directions of anisotropy of the tube, namely, axial, radial and circumferential, and the flow stress was determined as a function of specimen orientation, strain and strain rate over the temperature range 298-1200 K. The deformation behavior is analyzed in terms of the initial crystallographic texture of the tube and the deformation mechanisms operating at the various temperatures. The effect of stress state was also investigated at 298 K on specimens of axial orientation. The differences observed in the compression and tension behavior are discussed in terms of deformation mechanisms and the evolution of the texture.
