Conclusions
-
1.
During liquid metal quenching of alloy VT22 there is an increased solubility of carbon up to 0.3% in the bcc lattice of the β solid solution in titanium.
-
2.
Annealing of the rapidly quenched particles brings about decomposition of the supersaturated β solid solution, and precipitation of titanium carbide is primarily observed at the boundaries of the dendritic cells or the β grains, which prevents their growth during annealing,
-
3.
Increasing the annealing temperature from 600 to 800°C leads to a significant increase in the size of the titanium carbide precipitates and an increase in their quantity from 2.5 to 5%.
