Texture evolution during ARB (Accumulative Roll Bonding) processing of Ti–10Zr–5Nb–5Ta alloy

► Nanostructured/ultra-fine grained structure easily obtained by Accumulative Roll Bonding processing. ► Microstructure consisting in a mixture of α-Ti/α″-Ti phases. ► ARB precursor shows the presence of high intensity {022¯3}〈101¯0〉 and {011¯1}〈101¯0〉 texture components and high intensity basal fibre {0001}. ► ARB processed states shows the presence of high intensity {011¯0} fibre and low intensity {011¯2}〈101¯0〉 and {022¯3}〈101¯0〉texture components. Titanium alloys are extensively used in a variety of applications due to their good mechanical properties, high biocompatibility and corrosion resistance. In the last decade, α-type Ti alloys containing Zr, Nb and Ta have received much attention, because they exhibit not only high strength but also bio-corrosion resistance and high biocompatibility. A α-type Ti–10Zr–5Nb–5Ta alloy was processed by Severe Plastic Deformation (SPD) – Accumulative Roll Bonding (ARB) procedure and investigated with the aim to observe the texture development during ARB processing. Texture data for the (0002), (101¯0), (101¯1) and (101¯2) Pole figures (PFs) were obtained by X-ray experiments and Inverse Pole Figures (IPFs) and Orientation Distribution Functions (ODFs) were determined. The results showed presence of {022¯3}〈101¯0〉 and {011¯1}〈101¯0〉 texture components, {0001} basal fibre and {011¯0}, {112¯0}, {112¯3}, {112¯6} fibres.
