The phase content of ZrCrNi and ZrMn2 alloys with initial hexagonal MgZn2 (14) 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.
