Conclusions

  1. 1.

    Two types of microstructure have been found in alloys sintered in a range of temperatures in which eutectics unsaturated and supersaturated with titanium carbide can exist: a microstructure consisting of fine polyhedral TiC grains with jagged edges and one consisting of large TiC grains of spheroidal shape.

     
  2. 2.

    Two types of titanium carbide ring structure are possible: One forms as a result of the coalescence of fine grains around austenitic steel grains and the other as a result of diffusional dissolution of the alloying elements of the steel in the titanium carbide.
