Abstract
A continuous research in the field of special electrometallurgy was carried out in France during the last 20 years, and numerical models of remelting processes (ESR or VAR) have been developed. In close collaboration with the E.O. Paton Electric Welding Institute a theoretical (i.e. modelling) and experimental study of the nitriding process of a Ni-20 % Cr alloy was performed.
Keywords: vacuum arc remelting, consumable electrode, nickel alloy, fine-grain structure of ingot, nitriding, denitrid-ing, levitated droplet method, digital simulation, heat transfer, material transport
