Material Notes:
Cold Formable Medium-Strength AlloyFeatures: This binary, age hardening alloy combines the easy formability and weldability of commercially pure titanium with improved mechanical properties, particularly at temperatures up to 350°C. It is used in the annealed condition as sheet, forgings, and extrusions for fabricating components such as bypass ducts of gas-turbine engines. Its used spread to the airframe industry, following the development of an ageing treatment which raises room-temperature tensile properties by about 25%, and nearly doubles the elevated temperature properties. Such a material is particularly attractive since it can be formed in the soft condition, thus lowering fabrication costs. It is nonmagnetic.Typical heat treatment for this alloy: Anneal at 790°C for 1 hour and air cool. Solution heat treatment at 805°C for 1 hour with a rapid air cool. Aging heat treatment at 400°C for 8-24 hours with an air cool and then for 8 hours at 475°C with air cool.Data provided by TIMET.
