摘要	The effect of carbon addition on microstructural evolution was studied in a near-a titanium alloy (Ti-5.6Al4.8Sn-2Zr-1Mo-0.35Si-0.7Nd). It was found that flake and ribbon titanium carbides with a NaCl crystal structure formed in the as-cast alloys with carbon additions of over 0.17 wt pct. Flake carbide particles are the product of eutectic transformation and precipitate from the high-temperature beta phase. The ribbon carbide particles are primary phases formed prior to the nucleation of any metallic phases. The as-cast alloys with carbide precipitation after heat-treatment at beta(t)-30 degrees C followed by water quenching showed the spheroidization of a lamellae and partial dissolution of carbide particles. After annealing at beta(t)+15 degrees C, carbide particles are mostly distributed at the grain boundary and spheroidized through mixed grain boundary plus bulk diffusions.
