| Abstract Scope |
As a result of thermodynamic modeling, a mathematical model was proposed and implemented aimed at producing γ-TiAl alloys with a given structure and properties, based on the use of data on the features of physical modeling of the process of self-propagating high-temperature synthesis. . High-temperature synthesis of the γ-TiAl intermetallic compound in a powder mixture of pure elements makes it possible to obtain an intermetallic compound with an average grain size of ~ 30 μm. When solving the thermoforming problem of compression of γ-TiAl alloys, the following data were integrated into the Deform program: rheological properties of γ-TiAl alloys σ = f(ε, u, T), obtained experimentally on the Gleeble-3800 complex, which allows for numerical calculations of the kinetic dependencies of the main parameters of high temperature synthesis. |
