Conclusions

  1. 1.

    A study was made of structure formation during the annealing of titanium-base Ti-Cr3C2 composites. It is shown that during the annealing of extruded specimens at 950–1250°C the chromium carbide dissolves and a new phase, titanium carbide, is precipitated. An examination in a JSM-I3 scanning electron microscope established that the titanium carbide formed under these conditions is free from chromium, the reason for this being that the metallic matrix of the composite is in a state of disequilibrium.

  2. 2.

    Microhardness measurements were made on the structural phase constituents after annealing. The lowest value of titanium matrix microhardness was recorded for specimens annealed at 1150°C, a temperature at which titanium dissolves about 14% of chromium.
