The basic framework and - conceptual understanding of the metallurgy of Ti alloys is strong and this has enabled the use of titanium and its alloys in safety-critical structures such as those in aircraft and aircraft engines. Nevertheless, a focus on cost-effectiveness and the compression of product development time by effectively integrating design with manufacturing in these applications, as well as those emerging in bioengineering, has driven research in recent decades towards a greater predictive capability through the use of computational materials engineering tools. Therefore this paper focuses on the complexity and variety of fundamental phenomena in this material system with a focus on phase transformations and mechanical behaviour in order to delineate the challenges that lie ahead in achieving these goals.

The Ti60 titanium alloy, as one of high-temperature titanium alloys, has good creep resistance against high temperature, excellent thermostability at the servicing temperature of 600 C. The microstructure and the phases are investigated through Optical microscopy (OM), Scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD) after thermohydrogenation treatment of the Ti60 titanium alloy. The grains have been refined significantly through the thermohydrogenation treatment, and the occurrence and disappearance of the hydride phase is a main mechanism of grain refinement in the thermohydrogenation treatment of Ti60 titanium alloy.

Isothermal compressions of near-alpha Ti60 alloy were carried out on a Gleeble-3800 simulator in the temperature range of 960–1110 °C and strain rate range of 0.001–10.0 s 611. The high-temperature deformation behavior was characterized based on an analysis of the stress–strain behavior, kinetics and processing map. The flow stress behavior revealed greater flow softening in the two-phase field compared with that of single-phase field. In two-phase field, flow softening was caused by break-up and globularization of lamellar α as well as deformation heating during deformation. While in the single-phase field, flow softening was caused by dynamic recovery and recrystallization. Using hyperbolic–sine relationships for the flow stress data, the apparent activation energy was determined to be 653 kJ/mol and 183 kJ/mol for two-phase field and single-phase field, respectively. The processing map exhibited two instability fields: 960–980 °C at 0.3–10 s 611 and 990–1110 °C at 0.58–10 s 611. These fields should be avoided due to the flow localization during the deformation of Ti60 alloy.
