The precipitation of ZrCr2, which is a Laves phase with the C15 structure, in a supersaturated, martensitic matrix has been studied in a Zr-1.9 wt % Cr alloy using transmission electron microscopy. The nucleation, morphology and distribution of the precipitates has been examined at different tempering temperatures. The crystallographic orientation relationship between the α-Zr(Cr) and the ZrCr2 phases has been established and the precipitate habit plane determined.
