Ti-6Al-4V (UNS designation R56400), also sometimes called TC4, Ti64, [1] or ASTM Grade 5, is an alpha-beta titanium alloy with a high specific strength and excellent corrosion resistance.
Grades 1-4 are unalloyed and considered commercially pure or "CP". Generally the tensile and yield strength goes up with grade number for these "pure" grades. The difference in their physical properties is primarily due to the quantity of interstitial elements. They are used for corrosion resistance applications where cost, ease of fabrication ...
Commercially pure (99.2% pure) grades of titanium have ultimate tensile strength of about 434 MPa (63,000 psi), equal to that of common, low-grade steel alloys, but are less dense. Titanium is 60% denser than aluminium, but more than twice as strong [16] as the most commonly used 6061-T6 aluminium alloy.
The yield strength or yield stress is a material property and is the stress corresponding to the yield ... Cast iron 4.5% C, ASTM A-48 [5] 172 Titanium alloy (6% Al ...
Ti-6Al-2Sn-4Zr-2Mo (UNS designation R54620), also known as Ti 6-2-4-2, is a near alpha titanium alloy known for its high strength and excellent corrosion resistance. It is often used in the aerospace industry for creating high-temperature jet engines and the automotive industry to create high performance automotive valves.
Titanium aluminide (chemical formula TiAl), commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation [ 1 ] and heat, but has low ductility . The density of γ-TiAl is about 4.0 g/cm 3 .
When used on Grade 5 titanium it will produce an oxide layer 17.5 nm thick and a surface roughness of 3.4 um total height profile (R t). [7] In a chromic acid treatment the anodization is typically done at 5 or 10 volts. The 1982 study referred to above stated that the 5 volt performed better than the 10 volt as a function of average crack opening.
A UNS number only defines a specific chemical composition, it does not provided full material specification. Requirements such as material properties (yield strength, ultimate strength, hardness, etc.), heat treatment, form (rolled, cast, forged, flanges, tubes, bars, etc.), purpose (high temperature, boilers and pressure vessels, etc.) and testing methods are all specified in the material or ...
