Zonal Structure of Directionally Solidified Fe-Ni-Cu-S Materials

摘要

This paper examines the relationship between the phase diagram of a multicomponent system and the formation of primary zones in a directionally solidified material. The described general trends are illustrated by experimental data on the directional solidification of a melt with the composition (at %) Fe 35.0, Ni 5.0, Cu 10.0, and S 50.0. Primary zones were identified from chemical analysis data. To identify secondary zones, the phase composition of the ingot was determined by X-ray microanalysis, microstructural analysis, and X-ray diffraction.
