In situ formation of the composite structure of a eutectic Nb–Si alloy during directional solidification in a liquid-metal coolant

详细

The results of investigation of the structure of a heat-resistant eutectic niobium–silicon alloy, which was prepared by directional solidification using a liquid-metal coolant, are reported. The typical areas of the macrostructure of an ingot undergone directional solidification are considered, and the composition and the volume fractions of the Nb–Si composite have been determined.
