The results of TiC crystals and Ni microstructure studies by means of transmission electron microscope are presented. It was shown that Ni may be used as high temperature solvent for obtaining TiC crystals. This paper reports the results of morphology and growth of TiC crystals. The obtained TiC crystals with application of Ni as high temperature solvent were mainly of {001} cubic form, although irregular forms were also observed. Detailed TEM and HREM studies have shown that dislocations are formed in the vicinity of incoherent TiC precipitates in Ni matrices.

The results of TiC crystals and cobalt matrix microstructure studies by means of transmission electron microscope are presented. TiC crystals were obtained by the HTS method using cobalt as a high‐temperature solvent. The morphology of the obtained crystals was studied by physical metallurgy methods. X‐ray phase analysis of the obtained samples was also performed. It was found that TiC crystals are the primary crystals during solidification of the Co‐Ti‐C melt. No dislocation loops were revealed in the boundary region: TiC — martensitic cobalt matrix.
