摘要：

Transient segregation with second phase formation is studied for silicon sheet crystals grown from melts deliberately doped with iron and with chromium. Normal transients are modified by the second phase already after a few cm into growth. Second phases of iron and chromium appear in the form of spherical particles, sheet-like lamellae and filaments. Experimental data on the transient behavior and morphology of the second phases are related to segregation with eutectic phase formation.
