Cyclic-oxidation behavior of TiAl and of TiAl alloys
Oxidation of Metals, 1993The 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 ...

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.
