Abstract
The kinetics of hydrogenation of a two-phase deformed alloy based on the Ti2AlNb intermetallic compound in a temperature range of 700–900°C and the effect of hydrogen content and heating temperature on the formation of phase composition and structure are studied. Active and uniform hydrogen absorption of the alloy is shown to occur at low hydrogenation annealing temperatures. As the temperature increases, the hydrogenation intensity is found to decrease, and the growth of O-phase plates by 2–4 times is observed, which results in a decrease in the microhardness of the alloy.
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.
