Abstract

Рresents a review of current technologies for elinvarnyh alloys and their influence on the structure of the latter. It is shown that the main method of obtaining alloys is melting in induction furnaces. The heterogeneity of the structure and instability properties of these alloys requice finding other technologies for their preparation. Application of powder metallurgy in the manufacture of these alloys allows to obtain a more homogeneous structure, including through the use Nanodispersed powders. One aspect of improving properties elinvariv is to reduce the grain size.
