A method for separation and determination of TiC in in-situ TiC particle reinforced Fe_3Al based alloys has been investigated. The results obtained are summarized as follows : (1) When samples were dissolved in a 6N hydrochloric acid at 60∿80℃, TiC remained as a residue. TiC was separated from the acid solution by filtration. Amount and composition of separated TiC could be determined quantitatively. (2) Fe, Al and Cr in samples were detected as soluble elements in an acidic solution, while Ti was found in the insoluble residue (TiC). Mo was detected in both the acidic solution and insoluble residue. (3) Two types of TiC particles were observed. Large ones with sizes of about 5∿30μm have well developed facet structure, while small ones less than 1μm in diameter have dendritic structure. (4) Separation procedure along with the particle size was examined. Large particles were sedimented but small particles were dispersed in acetone, so they were able to be separated by filtration. Both large and small particles in samples are identified to TiC independent of the particle size.
