Abstract
Three compositions of the {Ni-25Cr-0.25 or 0.50C-1 or 2Ti}-type were studied by thermodynamic calculations for anticipating their melting temperature ranges and their microstructures at 1200 °C. In parallel the corresponding alloys were synthesized by classical foundry and subjected to Differential Thermal Analysis and exposures at 1200 °C followed by metallographic characterization. Calculations and experiments are globally consistent concerning the melting range temperatures, the microstructures in the as-cast state and after aging at 1200 °C. Good agreement was also found concerning the carbides fractions and the matrixes' chemical compositions.
