“…Laves phases and Nb-carbides NbC are known to form in eutectic reactions. The systematic study by DuPont et al [141][142][143], spanning from DTAexperiments and microsegregation analysis of fusion welded samples to modeling microsegregation and phase formation along the solidification path of various alloys, highlights the major role played by carbon.…”

“…The partitioning of Nb, Mo and Ti in the dendrite interstices during solidification (i.e., partition coefficient, k<1) promoted appreciable compositional variations in the solidification grain and substructural boundaries and the formation of terminal eutectic constituents (γ/NbC and γ/Laves) in the last-to-solidify regions [7][8][9][10][11][12]. The formation of the g/ Laves constituent results in a substantial suppressing of the final solidification temperature.…”
