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 ...

Isothermal oxidation of TiAl alloy

Metallurgical and Materials Transactions A, 2001
Isothermal oxidation behavior of Ti-48.6 at. pct Al alloy was studied in pure dry oxygen over the temperature range 850 °C to 1000 °C. The oxidation was essentially parabolic at all temperatures with significant increase in the rate at 1000 °C. Effective activation energy of 404 kJ/mol was deduced. The oxidation products were a mixture of TiO2 (rutile)

Review of alloy and process development of TiAl alloys

Intermetallics, 2006
Abstract The improved understanding of the factors that control microstructure and properties of TiAl alloys is reviewed together with current work aimed at developing both wrought and cast products. It is suggested that the choice of alloy composition is perhaps far simpler than the complex literature would suggest and the factors that underlie ...

TiAl formation by mechanical alloying

Materials Science and Engineering: A, 1992
Abstract Formation of equiatomic TiAl has been achieved through mechanical alloying of powders of two brittle compounds Al 3 Ti and TiH 2 . The influence of milling time, compaction of the powder by hot isostatic pressing, and elevated temperature exposure on the species and proportion of phases formed has been determined.

Mechanism of isothermal oxidation of the intel-metallic TiAl and of TiAl alloys

Oxidation of Metals, 1992
The oxidation behavior of Ti36Al, Ti35Al-0.1C, Ti35Al-1.4V-0.1C, and Ti35 Al-5Nb-0.1C (mass-%) in air and oxygen has been studied between 700 and 1000°C with the major emphasis at 900°C. Generally an oxide scale consisting of two layers, an outward- and an inward-growing layer, formed.
