Abstract
Based on the peculiarities of the copper-nickel alloy of vacuum melting Cu-45%Ni such as “constantan” (Russian abbreviation “МН45-ВП”), the reasons for the appearance of characteristic "tubercle" on the metallographic cuts of its rods as a type of surface effect of the "mustache" type are revealed. It has been shown that the formation of "tubercle" is a manifestation of diffusion processes caused by increased unevenness of the chemical composition of material. It is also indicated that the reason for this heterogeneity is due to the absence of special electromagnetic devices in the composition of the induction melting furnace for mixing the melt, the components of which are separated by indicators of magnetic susceptibility, i.e. the duration of the melt exposure during cooling during degassing is insufficient.
