Development of TiAl–Si Alloys—A Review [PDF]
Materials, 2021 This paper describes the effect of silicon on the manufacturing process, structure, phase composition, and selected properties of titanium aluminide alloys. The experimental generation of TiAl–Si alloys is composed of titanium aluminide (TiAl, Ti3Al or TiAl3) matrix reinforced by hard and heat-resistant titanium silicides (especially Ti5Si3).

Effects of plasma surface Ta alloying on the tribology behavior of γ-TiAl [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2021 To improve the wear resistance of γ-TiAl alloy, Ta alloy layer was prepared on surface by double glow plasma surface alloying technique. The tribology behavior of Ta alloy layer against Si3N4 at 25℃, 350℃ and 500℃ were comparatively studied.

Production of spherical TiAl alloy powder by copper-assisted spheroidization
Journal of Materials Research and Technology, 2023 A copper-assisted spheroidization method was developed for preparing spherical intermetallic compound TiAl powder. By introducing copper into TiAl alloy, the brittle L21 Heusler structure TiAlCu2 alloy with low melting point (1050 °C) was produced. After

On the Bauschinger effect in TiAl alloys [PDF]
Acta Materialia, 2016 Abstract The Bauschinger effect has been investigated at room temperature on a multiphase titanium aluminide alloy based on γ(TiAl). The effect of strain reversal was assessed by comparing uni-directional tensile tests with those performed on specimens made from pre-compressed material.

Combustion of TiAl alloy in nitrogen [PDF]
Combustion, Explosion, and Shock Waves, 2015 It 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.
