Abstract
The distribution of alloying elements over the phases in a eutectic Nb–Nb5Si3 composite material during directional solidification is studied. The influence of substitutional alloying elements on the type of structure in the reinforcing phase of silicide is analyzed. The crystal structures of the hexagonal and tetragonal modifications of the Nb5Si3 silicide are characterized and compared. The dependence of the creep resistance on the type of silicide structure is explained.
