AB This paper deals with the preparation of highly dense Ni-Ti alloys with addition of alloying elements like iron, vanadium and zirconium. The alloying elements were added in an amount of 5 wt. % into Ni-Ti46 wt. % powder mixture. The prealloyed NiTiX5 powder was prepared by the self-propagating high-temperature synthesis with following milling of the product. The prealloyed powder was consolidated by spark plasma sintering. The microstructures, mechanical properties and abrasive wear of prepared alloys were investigated. The results were compared with Ni-Ti and NiTiX alloys and other materials prepared by powder metallurgy. The undesirable changes in microstructures (formation of the Ti2Ni and Ni3Ti phases), the increase of hardness and abrasive wear resistance were found during milling and spark plasma sintering.
