The titanium and its alloys, despite being a relatively expensive class of metal, have important applications in the aerospace and medical industry. While its high specific strength makes them attractive in the aerospace field, where weight reduction is important, its excellent biocompatibility and great corrosion resistance make it a great choice for fabrication of orthopedic and dental implants. The oxide layer present in the surface of titanium-based components provides excellent corrosion resistance in aqueous mediums. Additionally, its lower elastic modulus, closer to that of the bone tissues, reduces the stress shielding effect. The Ti-35Nb-7Zr-5Ta alloy is a biocompatible beta-titanium alloy with low elastic modulus and high mechanical strength. It is free of toxic elements and is becoming an interesting choice for fabrication of implant devices. The control of crystallographic texture is a known way to modify properties and generate anisotropy in metallic materials. Mechanical strength, corrosion resistance and biocompatibility are some examples of properties that are dependent on the material's texture. The objective of this study is to evaluate the crystallographic texture evolution in the Ti-35Nb-7Zr-5Ta alloy after several processing routes involving rolling and recrystallization heat treatment. Texture will be measured by X-ray diffraction (XRD) and electron backscatter diffraction (EBSD). In a later stage, it will be analyzed the texture effect on the growth of TiO2 nanotubes on the surface of specimens. TiO2 nanotubes have important potential applications, including the improvement of implant osseointegration process.
