Definitions

  • the invention relates to the non-ferrous metallurgy, especially to the development of new titanium-base alloys offering high formability when seamless cold- worked tubes are manufactured for use in hydraulic systems of aerospace applications and sea vessels.
  • titanium alloys Due to their high strength, light weight and corrosion resistance titanium alloys are used in hydraulic systems of aerospace applications where pipe fittings are produced by welding or highly elastic pressing.
  • known titanium alloys have insufficient ductility to produce the fittings by elastic pressing.
  • alloy Ti-3A1-2.5V One of known industrial titanium alloys, used in the hydraulic systems, is the alloy Ti-3A1-2.5V. This alloy features high formability during cold rolling and allows to produce fittings by elastic pressing at minimum values of yield point 515 MPa and ultimate strength 620 MPa (AMS 4943D, Seamless Annealed Pipes for Hydraulic
  • Titanium alloy of the following composition in mass % is also known:
  • This alloy is applicable for hot working, may be used for manufacture of hot- worked and seamless cold-worked pipes, possesses a favorable combination of high strength, formability and corrosion resistance but its ductility is insufficient to flare the pipe or to produce fittings by elastic pressing.
  • the object of the invention is to propose titanium alloy possessing a combination of high strength, formability and corrosion resistance, suitable for manufacture of seamless cold-worked pipes for hydraulic systems of aerospace applications and sea vessels as well as for manufacture of pipe fittings by the elastic pressing method.
  • titanium-base alloy containing aluminum, vanadium, molybdenum, zirconium, iron, nitrogen and additional carbon at the following content of components, mass %:
  • This titanium-base alloy may also additionally contain palladium or ruthenium in the following quantities, mass %:
  • the high ductility during cold rolling and expansion of the pipes is achieved due to higher content of the ⁇ -phase which increases the plasticity as a result of large number of sliding planes in the crystal lattice and of the deformation of the ⁇ -phase within the ⁇ -phase under the isostatic compression.
  • zirconium and interstitial impurities content causes the increase in the ⁇ -phase quantity and strength but reduces the ductility.
  • Increase in the ⁇ -stabilizer content reduces the alloy stability, causes grain growth during the heat treatment which also reduces the alloy ductility.
  • the carbon content is below 0.01%, the yield point of the alloy is insufficient to ensure the performance capability of the piping in hydraulic systems.
  • the carbon content exceeds 0.1% the ductility of the alloy decreases at pipe expansion so that the pipe to fitting connection cannot be made by elastic pressing. Additional alloying with palladium and ruthenium in the claimed limits increases the corrosion resistance of the alloy in the marine environment when the alloy is used in sea vessel piping.
  • ingots with the composition shown in Table 1 have been melted in a vacuum arc furnace and pipes with the outside diameter of 1" and wall thickness of 0.051" were made from these ingots.
  • the mechanical and corrosion properties of the pipes are shown in Table 2.
  • the alloy with the claimed composition possesses high strength and ductility values in combination with high expansion and corrosion resistance and complies with the requirements for pipes used in hydraulic systems of aerospace applications and sea vessels.
  • the outside diameter expansion was determined as the ratio of the outside diameter of the specimen after flaring to the initial outside diameter.
