Abstract Scope |
Theoretical modeling of the thermodynamic processes of the release of excess phases that carried out using the CALPHAD method are presented, as well as a practical study of the structure and distribution of chemical elements in carbides, depending on alloying using SEM. It has been established that in carbides typical for the Ni-11.5Cr-5Co-3.6Al-4.5Ti-7W-0.8Mo-0.06C system, takes place a tendency to degeneration and phase reactions depending on the level of alloying with the given elements. The mathematical dependences of the influence of alloying on the temperature of precipitation (dissolution) of carbides and the change in the chemical composition of the alloy on the content of elements in carbides are established. The obtained dependences were experimentally confirmed using SEM on nickel-based superalloys. |
