Investigation of carbides in Ti-45Al-5Nb-xC alloys (0 ≤ x ≤ 1) by transmission electron microscopy and high energy-XRD

► Solid solution hardening is acting strengthening mechanism in Ti-45Al-5Nb-xC. ► Carbon solubility in high Nb containing TiAl alloys near 0.5 at.-% (as HIPed state). ► Detection limit for carbides appr. 0.1 vol.-% by HERD.
