Emissivity measurements conducted on intermetallic γ-TiAl-based alloys for aeronautical applications
Usategui Frías, Leire; López Ferreño, Iñaki; Echániz Ariceta, Telmo ; Sainz Menchón, Mireia; Musi, Michael; Clemens, Helmut; López, Gabriel Alejandro (Elsevier, 2023-11)The directional spectral emissivity of a Ti–48Al–2Nb–2Cr alloy (in at.%), 4822 alloy, and a Ti-43.5Al–4Nb–1Mo-0.1B alloy (in at.%),TNM alloy, used in the aeronautical industry, are measured between 150 and 850 °C. The ... -
High-temperature microstructure evolution of an advanced intermetallic nano-lamellar γ-TiAl-based alloy and associated diffusion processes
Nó Sánchez, María Luisa; Klein, Thomas; Clemens, Helmut; San Juan Núñez, José María (Elsevier, 2023-12)Nano-lamellar advanced γ-TiAl based alloys doped with small amounts of C and Si are being developed to improve the creep resistance in order to increase the performances of this kind of alloys applied in the low-pressure ... -
Influence of Nb on Ti Diffusion in Gamma-TiAl Intermetallics Studied by Mechanical Spectroscopy
Ibáñez Pérez, Josu; Nó Sánchez, María Luisa; Oehring, M.; Clemens, Helmut; San Juan Núñez, José María (Elsevier, 2021-01-25)The development of intermetallic titanium aluminides has been driven by the aeronautic and aerospace industries because of the excellent mechanical properties and low density of gamma-TiAl based alloys. Up to now, several ...
