| Description | 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. |
