Abstract—The results of experimental and statistical studies of the dependence of the mechanical properties of VT6 alloy rolled rods 20–155 mm in diameter on the chemical composition and lamellar structure parameters after various types of annealing are presented. Models to predict the ultimate tensile strength as a function of the α-phase lamella thickness and the structural aluminum and molybdenum equivalents are proposed. A strength diagram is constructed in the coordinates aluminum equivalent–α-lamella thickness–ultimate tensile strength at various molybdenum equivalents. The equivalents and structural parameters that provide the fulfillment of the requirements of industry standards are justified.

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.
