  2. Develop potential Ti-Ru-Al alloys for hi T applns in aerospace propulsion systems – replace Ni-base superalloys:

  3. Develop potential Ti-Ru-Al alloys for hi T applns in aerospace propulsion systems – replace Ni-base superalloys: Density ~ 30% lower 25-35% increase in specific strength possible

  4. Ti-Ru-Al alloys:

  5. Ti-Ru-Al alloys: • Phase diagram largely determined

  6. Ti-Ru-Al alloys: • Phase diagram largely determined • Little known about metallurgical characteristics or properties

  7. Ti-Ru-Al alloys: • Phase diagram largely determined • Little known about metallurgical characteristics or properties • Essentially unexplored territory with respect to applns as structural materials

  8. Interesting: • Ru - strong -Ti stabilizer…..stable over significant composition range from room temperature to 1550°C minimum

  9. Interesting: • Ordering rxn in Ti-Ru-Al  phase - possible strengthening beyond solid solution strengthening in titanium alloys

  10. Interesting: • Ti-2Ru-18Al alloy may be stable to ~900°C

  11. Interesting: • Ti-2Ru-18Al alloy may be stable to ~900°C • Ti-Ru-Al alloys with only few % Ru can be quenched from 1250°C to several different types of martensites - possible strengthening avenue
