In Situ Characterization of a Nb and Mo Containing γ‐TiAl Based Alloy Using Neutron Diffraction and High‐Temperature Microscopy

In recent times, novel titanium aluminides containing the bcc β ‐phase at high temperatures are being developed for improved hot‐working capabilities, however, predictions of the phase diagrams are merely uncertain. Here we present in‐situ neutron studies, which are particularly sensitive to the atomic disorder in the ordered phases. Complementary laser scanning confocal microscopy is employed for in‐situ microstructural investigations.
