Physical properties of TiAl-base alloys

Scripta Materialia, 2001
Abstract The physical properties of TiAl alloys were studied and compared with that of currently used high temperature materials. TiAl exhibits lower thermal expansion, higher specific stiffness and higher specific heat. The thermal conductivity of TiAl is comparable to that of superalloys and steels and higher than that of Ti–6Al–4V.

Advanced Intermetallic TiAl Alloys

Materials Science Forum, 2016
Challenging issues concerning energy efficiency and environmental politics require novel approaches to materials design. A recent example with regard to structural materials is the emergence of lightweight intermetallic TiAl alloys. Their excellent high-temperature mechanical properties, low density, and high stiffness constitute a profile perfectly ...

Cyclic-oxidation behavior of TiAl and of TiAl alloys

Oxidation of Metals, 1993
The cyclic-oxidation behavior of (in w/o) Ti-36Al, Ti-35Al-0.1C, Ti-35Al-1.4V-0.1C and Ti-35Al-5Nb-0.1C was studied between 800 and 1000° C in air. A few experiments were also performed in oxygen. Scale spallation after oxidation in air occurs during cooling on TiAl, TiAl-C, and TiAl-V at or close to the metal/scale interface when a critical scale ...

Crystal growth of TiAl alloys

Intermetallics, 1998
Abstract The growth of TiAl alloys over a range of Al concentrations has been considered for ingots processed by the floating zone technique. For Al-rich alloys, single crystals of γ-TiAl cannot be grown for compositions below Ti-54 at% Al since a banded microstructure forms due to the limitations imposed by the L + α → γ peritectic reaction. However,
