Plastic Instability in Irradiated Zr-Sn and Zr-Nb Alloys
SourceFactors affecting the plastic instability of irradiated zirconium alloys in tensile deformation have been studied. The materials used were pure zirconium, commercial Zircaloy-2 and Zr-2.5Nb, and a series of alloys based on pure zirconium containing either niobium or tin. The materials were rolled into thick sheet which enabled different crystallographic textures and deformation modes to be studied. Niobium alloy additions delay the onset of plastic instability and in some circumstances reverse the textural effects found in commercial Zircaloy-2 and Zr-2.5Nb. The merits of Zr-Nb alloys for use as fuel sheathing are outlined.
