Scripta Metallurgica, 1989
Abstract The results of this investigation are in agreement with the findings of Richards and Cahn which show that the formation of twin-related TiAl regions, TiAl T , and the Ti 3 Al phase, rather than TiAl deformation twins, will be favored energetically in a two-phase titanium aluminide alloy.

Preparation of TiAl/Mo and TiAl/NiAl composites by powder processing
Journal of Materials Science, 1997Processes for preparing TiAl/Mo and TiAl/NiAl composites are described and results of the investigation are reported. It was found that the hardness of the TiAl/NiAl composites was largely influenced by the amount of hard ternary phases formed through reactions between TiAl and NiAl.

Mechanical Properties of TiAl and TiAl-Base Alloys
1996Titanium forms three intermetallic compounds with aluminum. They are Ti3AI, TiAl and Al3Ti with crystal structures of the DO19, L10 and D022 types, respectively. They are superlattice structures based on geometrically close-packed h.c.p. and f.c.c. structures.

Mechanism of isothermal oxidation of the intel-metallic TiAl and of TiAl alloys
Oxidation of Metals, 1992The 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.

Pathways for microstructural development in TiAl
Materials Science and Engineering, 1988Abstract Rapid solidification processing (RSP) of intermetallic alloys can provide alternative solidification paths and lead to the formation of metastable products. For the intermetallic TiAl with an equilibrium L10 structure, RSP has yielded a metastable hexagonal close packed (h.c.p.) α-Ti phase in both fine powder and melt-spun ribbon.

Thermal formation of vacancies in TiAl
Physical Review B, 1994The formation of thermal vacancies, which is a key issue with respect to the high-temperature properties of ordered intermetallic compounds, was studied in \ensuremath{\gamma}-TiAl by means of positron lifetime spectroscopy between ambient temperature and 1400 K.

MRS Bulletin, 1994
The intermetallic compound, TiAl, and materials based on it have been receiving considerable attention because of their high specific strengths at elevated temperatures. Their mechanical properties are being extensively studied, with a view to application in aircraft or automobile engines.

Deformation Behavior of TiAl Compounds with the TiAl/Ti3Al Lamellar Microstructure
1992In the last few years, substantial progress has been made in our understanding of the microstructure and the deformation and fracture behavior of TiAl compounds. We have made uniaxial tension tests of specimens of the TiAl compounds whose lamellar orientation is controlled so that shear deformation occurs parallel to the lamellar boundaries only in the
