To increase the efficiency of the next generation of gas turbines, it is necessary to replace
the heavy Ni-based superalloys with lightweight materials that are resistant to high …

In this work, carried out within the European project TIALCHARGER, TiAl-based powders of
Ti-48Al-2Nb-0.7 Cr-0.3 Si, were used to fabricate specimens and prototypes of hollow …

This paper reports the activities carried out at the Department of Applied Science and
Technology of Politecnico di Torino about Titanium Aluminide alloys for aerospace and …

A two-layer TiAl/TiAlN coating was deposited by High Power Impulse Magnetron Sputtering
on the surface of three TiAl intermetallic alloys for improving their oxidation resistance. The …

The oxidation resistance in air of Ti-48Al-2Cr-2Nb, Ti-48Al-2Nb-0.7 Cr-0.3 Si, Ti-43.5 Al-4Nb-
1Mo and Ti-47Al-2Cr-8Nb alloys was investigated in the range of 800–1000° C. Specimens …

Hot corrosion behaviour of a fully lamellar Ti–46Al–8Ta (at.%) alloy was studied in air under
thermal cycling conditions (20-h cycles) at 700 and 800° C. The samples were purposely …

The influence of the environment on the properties of TiAl alloys is a concern for elevated
temperature applications. One element that stands out in improving the resistance of TiAl …

The formation process of the double continuous TiN/AlNb 2 protective oxide layers of TiAl-Ta
alloy after high-temperature oxidation is investigated by experiment and first-principle …

We studied the adsorption behavior of oxygen on low index surfaces of γ-TiAl via first
principles to investigate the mechanism that drives the adsorption behavior. The (100) …

Research on how thermal exposure affects the microstructure and mechanical properties of
the Ti–48Al–3Nb–1.5 Ta (at.%) alloy, which is prepared via powder hot isostatic pressing (P …
