In Situ High-Energy X-ray Diffraction during Hot-Forming of a Multiphase TiAl Alloy
Autor: Andreas Stark, Marcus Rackel, Aristide Tchouaha Tankoua, Michael Oehring, Norbert Schell, Lars Lottermoser, Andreas Schreyer, Florian Pyczak
Publikováno v: Metals, Vol 5, Iss 4, Pp 2252-2265 (2015)
Intermetallic γ-TiAl based alloys exhibit excellent high-temperature strength combined with low density. This makes them ideal candidates for replacing the twice as dense Ni base super-alloys, currently used in the medium temperature range (~700 °C

The Transformation Mechanism of β Phase to ω-Related Phases in Nb-Rich γ-TiAl Alloys Studied by In Situ High-Energy X-Ray Diffraction
Autor: Thomas C. Lippmann, Michael Oehring, Florian Pyczak, Andreas Stark, Lars Lottermoser, Andreas Schreyer
Publikováno v: Materials Science Forum. 772:85-89
In recent years intermetallic γ-TiAl based alloys with additional amounts of the ternary bcc β Ti(Al,Nb) phase attracted increasing attention due to their improved workability at elevated temperatures. Depending on alloy composition and heat treatm
