Explain about Extra low Interstitial
Extra low Interstitial (ELI) contains low levels of oxygen dissolved in interstitial sites in the metal. Lower amounts of oxygen and iron improve the ductility of the ELI alloy. Newer Ti alloys include Ti-13Nb- 13 Zr and Ti-15Mo-2.8 Nb. These alloys utilize other phase stabilizers than Al and V and may be more corrosion resistant.
