MODELING OF CARBIDES COMPOSITION IN WELDED ALLOY SYSTEM Ni-34Cr-4,3W-2,3Mo-1,3Al-1,3Ti-1,3Nb-0,1C
Keywords:weldable nickel-based superalloy, carbides, distribution alloying elements, temperature of precipitation carbides
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.
