Production of intermetallide compound Fe3Al by layer-by-layer electric arc growth method

Currently, additive technologies for layer-by-layer electric arc growth are being used. The main vector of development in this area is associated with the use of aluminum alloys. In this work, an experimental technique was tested for producing the Fe3Al intermetallic compound by layer-by-layer electric arc growth with the simultaneous supply of two dissimilar solid-section welding wires with diameters of 1.2 mm into the electric arc combustion zone. Methods for producing intermetallic compounds and their disadvantages are analyzed. Electric arc growing modes have been determined. The result of the experiment was the production of an iron-based alloy with an aluminum content of 13-16 %. The grown samples were subjected to heat treatment, after which the Fe3Al intermetallic compound was obtained.
