Abstract :
A comparison has been made between the phase equilibrium calculated within the Calphad method with different thermodynamic databases (TCFE7, TCNI5, TTNI7) and experimental data obtained on a Nb–Ti-modified industrial HP grade. The experimental measurements include phase equilibrium data at different temperatures and liquidus/solidus determination. The obtained agreement between experiments and calculations is generally good. Conclusions are made concerning the most suitable thermodynamic database to describe highly alloyed austenitic refractory steels.
