Abstract

Abstract

In order to explore the influence of the texture of the Zr-Sn-Nb alloy strip on its mechanical properties in different directions, the texture and mechanical properties in different directions of the finished annealed Zr-0.85Sn-1Nb-0.3Fe alloy strip were systematically analyzed by Electron Backscatter Diffraction (EBSD) and tensile test. The results showed that the typical bimodal basal texture was formed in the alloy strip, leading to the anisotropy of mechanical properties. With the increase of the angle between the loading direction and the RD (Rolling Direction), the Schmid factor of the main slip system in the strip showed a decreasing trend, which increased the opening difficulty of the slip system. Also the yield strength and yield ratio increased, while the tensile strength and work-hardening index decreased. As a result, the Zr-Sn-Nb alloy strip has relatively better stamping formability in the RD.
