Properties of Ti–6Al–4V Alloy Powders for Selective Electron-Beam Additive Manufacturing of Products
The properties of the powders used in additive manufacturing (AM), including electron-beam melting, of products have been studied. Defects in powder granules and the causes of their appearance are revealed. The recycling of the powders is found to bring about the appearance of cakes and agglomerates in their composition with a slight change in the particle size distribution. The microhardness of the powder particles is found to be 20–40 MPa higher than that of the samples constructed by electron-beam melting.
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.
