The phase content of ZrCrNi and ZrMn₂ alloys with initial hexagonal MgZn₂ (С14) type of Laves phase structure after reactive milling in hydrogen was investigated by X-ray powder diffraction and energy-dispersive X-ray spectroscopy. Depending on the milling time, the structure of the ZrCrNi alloy, which now contains significant amounts of Fe, changes from MgZn₂ type to MgCu₂ and Th₆Mn₂₃ type structure after heat treatment.
