Abstract
A near-α transformation-induced plasticity (TRIP) titanium (Ti) alloy is designed by using a thermodynamic database and a mobility database of Ti alloys for α, β, and TiAl phase equilibria and diffusive processes; based on experimental data, creating a thermodynamic and kinetic database for β-to-α'/α″ martensitic transformations in the Ti alloys; creating a molar volume database for the β-to-α′/α″ martensitic transformations in the Ti alloys at room temperature; and obtaining an overall composite of the near-α TRIP Ti alloy by adjusting a reference overall composite of a reference near-α Ti alloy based on the created thermodynamic database, where the reference near-α Ti alloy is Ti-5Al-1Sn-1Zr-1V-0.8Mo-0.1Si-0.1Fe-0.1O by weight percentage (Ti-5111), and wherein the near-α TRIP Ti alloy is Ti-8Al-1V-1Sn-1Zr-0.6Mo-0.9Fe-0.1Si-0.1O by weight percentage.
