What is Titanium Alloy?
Titanium alloy Ti6Al4V is a medium-strength α-β type two-phase titanium alloy containing 6% α-stabilizing element AI and 4% β-stabilizing element V. This alloy has excellent comprehensive properties and has obtained the most extensive applications in the aviation and aerospace industries.
The main properties and uses
Ti6Al4V titanium alloy is heated below 430 ℃ for a long time to form a very thin and protective oxide film. As the heating temperature increases, the oxide film thickens and its protection becomes poor. After the alloy was heated at 700 °C for 2 h, the oxide film thickness reached 25 μrn. Heating at temperatures above 800°C forms a sparse oxide layer. After heating at 1000 °C for 1 h, the thickness of the oxide layer reached 0.65 mm.
Ti6Al4V alloy can be welded by argon arc welding, spot welding, brazing, electron beam welding and plasma welding. The strength of the welded joint is basically the same as that of the base metal.
When Ti6Al4V titanium alloy parts are in contact with aluminum alloy and structural steel parts, especially under certain corrosive medium conditions, aluminum alloy and structural steel parts will suffer accelerated corrosion and damage as the anode of the contact couple due to the negative electrode potential. Therefore, between TC4 titanium alloy parts and aluminum alloy or structural steel parts, protective measures such as padding and anti-corrosion tape should be taken. TC4 alloy parts are strictly prohibited from contact with parts or tools of lead, zinc, cadmium, tin, silver, bismuth and other metals.
Before vacuum annealing, the oxide skin and oxygen-rich layer on the surface of the parts should be removed, and the oil should be carefully removed before entering the furnace. When vacuum annealing parts with complex shapes, fixtures must be used to reduce the deformation of parts. Into the furnace parts are preferably filled with pre-degassed titanium oxide-free chips to prevent oxidation of the parts.
Ti6Al4V titanium alloy is now widely used in the manufacture of aero-engine fans and compressor discs and blades, as well as various load-bearing beams, frames, joints and fasteners in aircraft structures.
