Abstract

V originále

This work is focussed on microstructure studies of the Ni-Al-W system for selected compositions within the phase regions of interest (gamma,gamma', alpha, beta and/or other intermetallic phases) at 900, 1000 and 1100 C. Experimental results were compared with existing literature information and all data utilized for thermodynamic assessment of this ternary system by using optimization module PARROT in the well-known software package ThermoCalc. The commercial database for Ni-base superalloys was used as a source database for the process of optimization and the data were fitted with respect to newly obtained experiments as well as to the thermodynamic parameters found previously.

In Czech

Práce je zaměřena na mikrostrukturní studia soustavy Ni-Al-W v oblastech koexistence fází gama,gama', alfa, beta případně dalších intermetalických fází při 1000 a 1100 C. Experimentální výsledky byly srovnány s existujícími literárními informacemi a data použita pro termodynamické posouzení této třísložkové soustavy za pomocí modulu PARROT v programu ThermoCalc. Pro optimalizaci dat byla jako zdrojová databáze použita komerční databáze pro niklové superslitiny.
