Abstract
The possibilities of a new method for producing an Fe–Cu composite material based on an additive coaxial laser melting technology are investigated. Melting conditions, powders, and growing strategy are chosen. The microstructures of the following compositions were studied (%): 75Fe–25Cu, 50Fe–50Cu, and 25Fe–75Cu. The structure of these materials is found to be a copper matrix with uniformly distributed iron particles. No separation of the elements in the track volume is detected. There is no porosity. Electron microscopy has shown that the solubility of the elements in each other is minimal, no more than 2–3%. Samples up to 10 mm thick with a uniform iron distribution in the copper matrix volume are fabricated by superimposing tracks on each other in both horizontal and vertical directions. The possibility of producing a material by melting steel and bronze powders taken in the ratio 40% AISI316 and 60% BrKh0.8 without separation has been demonstrated.
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.
