... to line nearly all of the energy producing wells in this field. The material proved to be an excellent choice and has given 20-25 years’ service life to date. Despite its excellent performance, Grade 29 is a high strength titanium alloy that is expensive to manufacture and finish. Recent wells (2012...

... Modern structural biomedical implants are made from titanium alloys due to their excellent corrosion resistance and biocompatibility. Currently UNS R56400 (Ti64), the most common structural implant material, provides 12-15 years of service 1 . Increasing the longevity of implants is becoming important...
