| Popis: | The paper provides the results of statistical research of the mechanical properties of deformed semi-finished titanium alloys Ti-6Al-4V and Ti-10V-2Fe-3Al, based on the industrial data analysis. The research objects were 1.635 forging products, made of the alloys ВТ6 (Ti-6Al-4V) and Ti-10-2-3 (Ti-10V-2Fe-3Al), manufactured in compliance with the industrial technology. The statistical research conducted with the help of the applied software package "Stadia 7" included the primary statistical manipulation and a correlation-regression analysis with the help of standard methods. The authors established correlation relationships between the mechanical properties of such semi-finished products containing alloying elements, admixtures and the industrial modes of the strengthening heat treatment. It was revealed that the variations in the grade composition, hardening and aging temperature can determine 10-40% of variable forging mechanical properties. The key variation is pre-determined by the factors the authors failed to identify on the basis of the data research. |
