MODELING OF CARBIDES COMPOSITION IN WELDED ALLOY SYSTEM Ni-34Cr-4,3W-2,3Mo-1,3Al-1,3Ti-1,3Nb-0,1C

Abstract

In this work, theoretical modeling of the thermodynamic processes of the release of excess phases is carried out, as well as a practical study of the structure and distribution of chemical elements in carbides, depending on alloying using a scanning electron microscope. The obtained dependences were experimentally confirmed using X-ray spectroscopy on nickel-based superalloys. It is recommended to use the obtained mathematical models not only in the design of new nickel-based superalloys, but also in the improvement of known brand compositions within the declared concentrations.
