A late stage of abnormal grain growth, having unusual planar abnormal growth interfaces, is observed during the isothermal annealing of electrodeposited nanocrystalline Ni and Ni-Fe alloys. This communication presents observations of grain embedding and the presence of a wetting, sulfur-rich second phase at the abnormal growth interface and suggests a growth mechanism.
