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 ...

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 ...

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.

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.

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.

Thermomechanical fatigue of titanium aluminides
International Journal of Fatigue, 2013Abstract This paper reviews the thermomechanical fatigue (TMF) studies performed on various titanium aluminide (TiAl) alloys during the last decade in the research group of one of the authors (H.-J. Christ). The investigated alloys are Ti–47Al–2Mn–2Nb (XD), Ti–46Al–4(Cr, Nb, Ta, B) (γ-MET), Ti–45Al–5Nb–0.2C–0.2B (TNB-V5) and Ti–45Al–8Nb–0.2C (TNB-V2).

The mechanical alloying of titanium aluminides
JOM, 2002This article reviews the mechanical alloying of titanium aluminides carried out in the past decades. Research has proven that mechanical alloying is an efficient means to synthesize nano-structured and non-equilibrium titanium aluminides. Although fine-grained structures have been successfully produced, effort is still needed to reduce contamination ...

Coating of Sic on Titanium Aluminide
MRS Proceedings, 1992Coating of silicon carbide on the surface of structural materials is being used in industry to improve the oxidation resistance and wear resistance properties. In this study, silicon carbide coatings were applied on titanium aluminide by both chemical vapor deposition and sputter deposition techniques.

The Alloying of Titanium Aluminides with Carbon
MRS Proceedings, 1988ABSTRACTAn investigation has been made on the constitution of the Ti-Al-C system in the range of 15–55 at% Al and of 0.1–1.0 at% C and the temperature range of 1250–450 °C. Equilibria including three compounds TiC, Ti3AlC, and Ti2AlC have been studied and transmission electron microscopy (t.e.m.) observations of ordering reactions in az have been made.
