What is titanium aluminide alloy?
Titanium aluminide, TiAl, commonly gamma titanium, is an intermetallic chemical compound. It is lightweight and resistant to oxidation and heat, but has low ductility. The development of TiAl based alloys began circa 1970. The alloys have been used in these applications only since about 2000.
What is titanium aluminide used for?
Powder metallurgy titanium aluminide alloys Titanium aluminide (TiAl)-based alloys are developed for high-temperature applications in aerospace and automotive industries because of their attractive properties, such as low density, high specific strength, high specific stiffness, and good high-temperature properties.
What is the hardness for titanium?
70 to 74 HRB
Titanium Properties
| Property | Value |

What is the density of titanium?
4.5 grams per cm3
Its density is 4.5 grams per cm3, much less than iron, so titanium alloys are important in the aerospace industry.

Is aluminide a metal?
An aluminide is a compound that has aluminium with more electropositive elements. The properties of an aluminide are between those of a metal alloy and those of an ionic compound.
Who invented titanium aluminide?
AMG
Light-weight Alloys AMG has innovated a number of specialty alloys and coatings used to help reduce weight and improve the operational performance of aircraft. Through extensive research beginning in the mid 1990s, AMG developed titanium aluminides (TiAl).
Why does titanium have a high tensile strength?
Titanium contains trace amounts of impurities such as iron and atomic oxygen, and they have the beneficial effect of increasing strength and hardness by solid solution hardening. For example, ultra-high purity titanium (with an oxygen content of under 0.01%) has an ultimate tensile strength of about 250 MPa.
What are the mechanical properties of titanium aluminides?
Titanium aluminides offer an attractive combination of low density and good oxidation and ignition resistance with unique mechanical properties. These involve high strength and elastic stiffness with excellent temperature retention.
Which aluminide system has the best specific properties?
Titanium aluminide alloys have the lowest densities among the three common aluminide systems and thus offer the best specific properties. The phase diagram in Figure 4 shows that Ti 3 Al and TiAl have similar ranges of stoichiometry.
What are the challenges in attaining corrosion resistance of titanium?
The high reactivity of titanium creates challenges in attaining corrosion resistance, as will be discussed later, as well as in reliable alloy production. Figure 4. TiAl phase diagram.
Why are titanium aluminides not used in aircraft engines?
However, titanium aluminides are susceptible to brittle fracture owing to their low ductility and poor fracture toughness, and this is a key factor stopping their use in aircraft engines. Typically, titanium aluminides have a room temperature ductility of 1–2% and a fracture toughness of about 15 MPa m −0.5,…
