Tóm tắt

The mechanical properties of deformed semifinished products made of titanium alloys manufactured at different enterprises in the period from the 1970s to the present time are studied. The statistical dependences of the standard mechanical properties on the chemical composition, structure, annealing conditions, and test temperature are revealed from the generalization of the published data and results of industrial tests, industrial control, and own experiments. Recommendations aimed at enhancing the quality of the semifinished products from Ti–6Al–4V alloys are proposed. A prototype has been developed for a “Titanium Alloys” automated information system with the possibility of predicting the properties of titanium alloy semifinished products.
