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.

Processing titanium aluminide foils
JOM, 1989In an effort to extend the available manufacturing technologies for Ti3Albase aluminides, the potential success of a new hot-rolling process for the production of high-quality foils has been investigated. Processing of Super-α2 aluminide foils approximately 0.15 mm thick takes full advantage of the combined benefits of controlled rolling and a unique ...

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 ...

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
