Special Issue Information

Dear Colleagues,

Titanium and its alloys have become essential materials in a variety of high-performance industries due to their exceptional combination of specific strength, biocompatibility, and corrosion resistance. These unique properties make them ideal for aerospace, biomedical, defence, and chemical applications, where reliability in extreme conditions is essential. As technological demands continue to evolve, the development of advanced titanium alloys is increasingly relevant.

To fully realise their potential, processing steps need to achieve fine control over alloy composition, microstructure, and mechanical properties. However, the processing of titanium is challenging due to the metal’s high reactivity with other elements, particularly oxygen. Ongoing research aims to enhance production efficiency and expand the use of titanium alloys in emerging technologies.

This Special Issue brings together the latest studies on titanium alloys, covering advances in processing techniques, property enhancements, and the expansion of applications. Contributions are encouraged on topics such as novel manufacturing methods, alloy design, mechanical behaviour, and responses to real-world environments. The research presented will highlight the continuing importance of titanium alloys in modern engineering and their growing role in future technological innovations.

Ti-Nb alloys have been under active consideration for superelastic applications in biomedical devices due to their superior biocompatibility compared to NiTi. However, these alloys have been found to be highly sensitive to processing conditions, with many studies measuring different transformation temperatures for the same alloy composition. Several processing factors, including heat treatment times, temperatures and cooling rates, have been investigated. However, the effect of the rolling ratio on superelastic properties has not yet been systematically considered. In this study, samples of Ti-24Nb-4Zr-8Sn (wt%) with varied cold rolling reduction ratios were produced, and the superelastic properties were characterised. After the heat treatment, all samples were found to be predominantly in the metastable cubic β phase, with a small, non-varying volume fraction of the ω phase also present. Electron backscattered diffraction was utilised to measure the resulting texture and grain size in each sample, and these values were correlated to the superelastic properties. Full article

Metastable titanium alloys have been developed for biomedical use due to their lower elastic modulus, combined with high strength, good ductility, and excellent corrosion resistance. In this study, the electrochemical corrosion resistance of the alternative Ti-23.6Nb-5.1Mo-6.7Zr alloy was investigated. The alloy was initially homogenized at 1000 °C for 24 h and then tested under different processing conditions: 90% cold rolling; 90% cold rolling followed by annealing at 950 °C for 1 h and water quenching; and 90% cold rolling followed by aging at 300 °C, 400 °C, and 500 °C for 4 h each. Electrochemical behavior was assessed using anodic polarization, open circuit potential (OCP), and electrochemical impedance spectroscopy (EIS) tests in a synthetic solution (Ringer’s solution) to simulate body fluid. The obtained results demonstrate the stability of the passive film formed of the conventional and modified alloys, considering long-term use in the human body, regardless of the volumetric fraction and phase distribution across the various processing routes studied as β, α, α″ and ω. The electrochemical parameters, combined with Young’s modulus and hardness of the alternative alloys, enable the definition of a multicriteria selection method of the most suitable mechanical process routes to be used. The application focused on components of functional femoral stems. Full article
