The microstructure and microhardness of Ti-20Nb-7.5Ta and Ti-20Nb-10Ta alloys (at. %) after smelting and after homogenizing annealing at 900°C and 950°C for 12 hours were studied. It was shown that, after smelting, the alloys have a dendritic structure, and after annealing, they have a polycrystalline structure with equiaxed grains. It is also shown that annealing leads to an increase in the microhardness of alloys.
