Fatigue properties of TiAl alloys

Intermetallics, 2005
Abstract The fatigue properties of TiAl alloys, namely fatigue life, cyclic stress–strain behaviour and fatigue crack growth resistance are reviewed in the present paper. The influence of different parameters (microstructure, defects, temperature and environment) on these properties is examined. Finally, some considerations on the fatigue reliability

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 ...

Alloy and process development of TiAl

Journal of Materials Science, 2004
The development of cast TiAl-based components for the automotive industry and the possibility of wrought components for applications in gas turbines are clear indications that these alloys are maturing as materials for engineering components. There are however problems in the cost of manufacture and in the properties of these alloys.

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)

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.

Itinerant antiferromagnetism of TiAl alloys

Journal of Magnetism and Magnetic Materials, 1986
Abstract Magnetic susceptibility measurements of TiAl alloys are reported. Aluminium, by alloying, acts on the Neel temperature of pure titanium giving rise to a complicated phase diagram. A theoretical model, based on the itinerant antiferromagnetism model of chromium is proposed in order to explain the magnetic phase diagram of TiAl alloys.

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.
