Abstract—The influence of the globular structure parameters and the chemical composition (based on aluminum and molybdenum equivalents) on the mechanical properties of rolled VT6 titanium alloy bars (16–90 mm in diameter) after annealing treatment under various conditions is studied. The most significant microstructural factors contributing to different strength levels are revealed by statistical analysis. A ultimate tensile strength prediction model is developed on the basis of α-phase particle size and alloying-element and impurity equivalents (aluminum and molybdenum equivalents). The values of these equivalents and globular structure parameters are determined to meet industry standard requirements.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
