Melting of multicomponent, refractory alloys in an induction furnace under gas‑vacuum conditions

The paper considers the advantages of induction melting in a vacuum environment, ensuring the production of high‑alloy alloys based on refractory components, free from harmful impurities with specified properties. The processes occurring in alloys during melting, holding and pouring are considered. The resulting alloys are primarily planned to be used as protective coatings for composite materials. These alloys include refractory wear‑resistant alloys, such as the Cu–Ti system and high‑entropy alloys, which are compositions containing from 5 to 13 elements with approximately equal concentrations. The structure of the resulting material and the distribution of elements over the ingot cross‑section are presented.
