Abstract

The article provides the results of statistical research on the dependence of the mechanical properties of bars with a 14 mm diameter, made of the titanium alloy VT22, on the heat treatment modes and the chemical composition on the basis of the analysis of experimental, literature and manufacturing data. The authors study the correlation between mechanical properties and the content of alloying elements, admixtures, heat treatment modes. The research finds out regression dependences to evaluate the average values of the mechanical properties of the bars 14х14 mm of the alloy VT22 on the annealing temperature (within an hour, furnace cooling up to 4000С, and further air cooling) and the equivalents of alloying elements and admixtures on aluminium and molybdenum.
