The phase formation upon rapid cooling by copper mould casting of a Zr‐Cu‐Al‐Ni alloy with two different oxygen contents is reported. The nominally oxygen‐free alloy produces a glassy phase, whereas the presence of 0.56 at.% oxygen results in crystallization. The crystalline phase selection is governed by the cooling rate. The microstructure and mechanical properties as well as the correlation between them in the oxygen‐containing alloy were investigated.
