Beschreibung
Nb-MASC (niobium–metal and silicide composites) alloys are promising candidates for manufacturing innovative turbine components but present major manufacturing challenges due to melt reactivity and chemical inhomogeneities. This work proposes induction melting and alloying of Nb-MASCs in a cold-wall crucible furnace to overcome these limitations. Electromagnetic forces generated during induction melting enhance mixing, promote homogeneous distribution of alloying elements, and consequently mechanical reinforcement of the manufactured cast. This study integrates numerical simulations and experiments: Eulerian mixture models and Lagrangian discrete phase models are used to predict elemental transport within the melt. Experimental investigations identify optimal melting and alloying conditions to enable an efficient and reproducible melting route.
