The microstructure including layer-by-layer elemental composition of rapidly solidified Al-6.0; 9.4; 15.0 Zn (at %) alloys has been examined. Three distinct types of microstructure are found out in a transverse cross-section of the foils. Nonuniform Zn depth distribution shows depletion of thin (0.02 ěm) surface layers by Zn. The zone at contact foil surface has the highest microhardness value. The effect of Zn content on pattern formation in rapid solidification of the alloys with respect to microhardness on foil transverse cross-section was summarized.

Mikrostruktura stopów Al-6.0; 9.4; 15.0 Zn (w%) otrzymanych w procesie szybkiego zestalania została zbadana włącznie z analizą składu pierwiastkowego warstwa po warstwie. W przekroju poprzecznym folii wyróżniono trzy różne typy mikrostruktur. Nierównomierny rozkład głębokościowy Zn wykazuje zubożenie cienkich (0,02.m) warstw powierzchniowych w Zn. Strefa na powierzchni styku folii charakteryzuje się najwyższą wartością mikrotwardości Omówiono wpływ zawartości Zn na powstawanie struktur krystalicznych w procesie szybkiego krzepnięcia tych stopów w odniesieniu do mikrotwardości na przekroju poprzecznym.
