In order to acquire TiAl composites with a multi-scale reinforcing phase, and to improve the microstructure and tensile properties at elevated temperatures, TiAl alloys have been prepared with different added carbon content levels via vacuum arc melting.

In recent years, an innovative twin-wire plasma arc additive manufacturing (TW-PAAM) process is conducted to the in situ alloying of TiAl alloys. As a newly invented method of TiAl alloy fabrication, the microcrack defect is a great concern.

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 ...

Solidification of TiAl-based alloys [PDF]
MRS Proceedings, 2008 AbstractTitanium aluminides containing high niobium additions emerged as an attractive alloy family for automotive and aero-engine applications. Their processing by near net shape casting is rather demanding, not only due to easy contamination but also due to the fact that microstructure formation during solidification and subsequent solid state ...

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,

Combustion of TiAl alloy in nitrogen
Combustion, Explosion, and Shock Waves, 2015It has been shown that Ti–Al–N ternary compounds, belonging to MAX phases (ceramic materials that can be processed as metals) can be produced by combustion of a granular powder of T65Yu35 (TiAl) alloy in nitrogen flow at a pressure close to atmospheric pressure. Combustion is accompanied by transfer of part of the aluminum through the gas phase.

The forging and rolling behavior of binary Ti-48Al and ternary Ti-48Al-2Cr (at-%) on laboratory and industrial scale is investigated. Arc-melted and cast ingots are used for forging operations. In order to enable the determination of optimized forging and rolling conditions the plastic flow behavior was examined for low ( −2 s −1 ) and high (1 s −1 ...
