Deformation behavior of cold-rolled and annealed Zr–1.5Nb and Zr–1.5Nb–S alloys

In this study, the effect of sulphur on the deformation behavior of cold rolled and annealed Zr–1.5Nb, Zr–1.5Nb–S alloys were studied. The beneficial effect of sulphur on the strengthening was observed both in the cold rolled and annealed Zr–1.5Nb–S alloys. The loss of ductility was intensified with the addition of sulphur in the annealed Zr–1.5Nb–S alloys in the region of dynamic strain aging, implying the interdependent effect of oxygen and...
