A technology for producing a Ti–26Nb alloy is developed. The effect of heat treatment conditions on the structure and the phase and chemical compositions of ingots is studied. Optimum homogenizing annealing conditions (900°C, 12 h) are found, which leads to the formation of a completely recrystallized structure. After melting, the alloy is found to be represented by a mixture of 66.5 vol % βm-Ti and 33.5 vol % α'-Ti with the bcc and orthorhombic crystal lattices, respectively. After annealing, the phase composition is shown to change to the continuous β phase with traces of the ω phase, which increases the microhardness of the alloy. After annealing, a homogeneous distribution of chemical elements over the entire volume is observed. The oxygen, nitrogen, carbon, and sulfur contents correspond to standard specifications for titanium alloys.
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.
