This paper reports the 1,000--1,200 K slow plastic deformation properties of TiC-modified Ti-48Al-2Cr-2Nb materials and compares their values with those of other TiAl-based alloys. Ti-46Al-2Cr-2Nb has been alloyed with TiC in an attempt to improve the 1,000--1,200 K strength by the formation of AlTi{sub 2}C precipitates in a lamellar matrix. While the addition of 6 wt.% TiC does improve strength under lower temperature or faster test conditions, at higher temperatures or lower strain rates the base Ti-46Al-2Cr2Nb alloy has better properties than the TiC modifications.
