Machinability of titanium aluminides: A review
Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications, 2018Titanium aluminides are used in the aeronautical and automotive field as an alternative material to manufacture critical components exposed to high temperatures and corrosive environments. These alloys due to its intermetallic structure exhibit some special properties such as low density, high strength, high stiffness, corrosion resistance, and creep ...

Titanium Aluminide Intermetallics
2012Abstract Titanium aluminides are lightweight materials that have relatively high melting points and good high-temperature strength. They also tend to be stronger and lighter than conventional titanium alloys, but considerably less ductile.

Twin toughening in titanium aluminide
Acta Metallurgica et Materialia, 1991Abstract The mechanical behavior of a γ-TiAl that exhibits mechanical twinning has been investigated. This material has been shown to have a relatively high toughness compared with that of other γ-TiAl materials, which do not twin. The tough material forms a wide twin process zone upon crack propagation.

The effects of hydrogen on titanium aluminides
JOM, 1991Advanced aerospace systems such as the national aerospace plane are slated to use hydrogen as a fuel. Thus, caution must be exercised in the use of materials which can exhibit degradation in mechanical properties on exposure to hydrogen. Although recent work shows that hydrogen has adverse effects on titanium aluminides, it can also be used to advan ...

Intermetallics, 2005
Abstract A range of mechanical properties for wrought TNB alloy (Ti–45Al–8Nb–0.2C%) and cast Ti4522XD(Ti–45Al–2Nb–2Mn–XD) have been assessed. The influence of notch sensitivity on fatigue strength has been evaluated and compared in terms of different microstructure and alloy composition.

Fatigue and Fracture of Titanium Aluminides
1990Abstract : Future tactical aircraft engine designs depend heavily on advanced materials technology to meet thrust-to-weight and durability goals. Several types of materials currently under development are candidates for use in these advanced engines, including intermetallic titanium aluminides. Titanium aluminide alloys offer low density, high specific

Transport properties of titanium aluminides
Materials Science and Engineering: B, 1995Abstract Low temperature resistivity studies are conducted on four single-phase Ti3Al alloys including the stoichiometric compound (25 at.% Al) in the temperature range 100–300 K using the standard four-probe measurement technique. A systematic order-dependent resistivity variation with temperature has been observed as the alloy composition deviated ...
