【 摘 要 】

The formation of the Ti-(20-30) Nb-5Zr alloys (at.%) structure was studied. The structure of the samples was determined using an light microscope. It is shown that after melting by the method of vacuum arc melting, the alloys have a developed dendritic structure. Homogenizing annealing at a temperature of 900 °C does not lead to the destruction of the dendritic structure and recrystallization. Annealing at a temperature of 1000 °C completely destroys the dendritic structure in the alloys.
