LaNi5 nano-powders with additions of Ce, Mn, Co (high and low content of cobalt) and Al were obtained by means of MBN technology, based on the high energy ball milling with different energy and protective atmosphere (Ar or H2). The microstructure and composition of all prepared nano-powders were investigated using the TEM/HRTEM, SEM/EDS, XRD and XPS techniques. Research showed that used technology allowed to produce materials distinguished by a fine and homogeneous chemical distribution of elements and an "ultrafine" (the nanometric size) crystalline structure. The results were then related to the preparation conditions.
