A 1948 graduate of MIT, Stanley Abkowitz (1927-2017) was a pioneer in the titanium industry and is credited for the invention of the Ti-6Al-4V during his time at the US Army’s Watertown Arsenal Laboratory in the early 1950s. [4] Titanium/Aluminum/Vanadium alloy was hailed as a major breakthrough with strategic military significance.
Grade 38 contains 4% aluminium, 2.5% vanadium, and 1.5% iron. This grade was developed in the 1990s for use as an armor plating. The iron reduces the amount of Vanadium needed as a beta stabilizer. Its mechanical properties are very similar to Grade 5, but has good cold workability similar to grade 9. [35]
A titanium cylinder of quality "grade 2" Titanium is used in steel as an alloying element (ferro-titanium) to reduce grain size and as a deoxidizer, and in stainless steel to reduce carbon content. [11] Titanium is often alloyed with aluminium (to refine grain size), vanadium, copper (to harden), iron, manganese, molybdenum, and other metals. [96]
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.
In the direct powder rolling (DPR) process BE powder is used to produce sheet and plate and composite multilayered sheet and plates. Sheets between 1.27 and 2.54 mm and 50 to 99+% dense of single layer CP titanium, Ti Grade 5, TiAl (Ti-48Al-2Cr-2Nb) and composite Ti/Grade 5/Ti and Grade 5/TiAl/Grade 5 have been produced by DPR and sintering.
Titanium Beta C refers to Ti Beta-C, a trademark for an alloy of titanium originally filed by RTI International. [1] It is a metastable "beta alloy" which was originally developed in the 1960s; Ti-3Al-8V-6Cr-4Mo-4Zr, nominally 3% aluminum , 8% vanadium , 6% chromium , 4% molybdenum , 4% zirconium and balance (75%): titanium .
The ATI 425 Titanium Alloy is a titanium alloy developed and produced by Allegheny Technologies Incorporated (ATI). It is produced in multiple product forms, including sheet, coil, strip, Precision Rolled Strip and foil, plate, seamless tube, shapes and rectangles, as well as castings.
[7] As shown in the above table, alloying is one of the effective methods to improve the mechanical properties and since Niobium belongs to the same group of Vanadium in the periodic table it is of course acts as α –β stabilizing elements (similar to Ti-6Al-4V alloy), however the strength of Nb alloy is little less than that of Ti-6Al-4V .The main difference between Ti-6Al-4V and Ti-6Al ...
