Nanostructured TiNi0.8B0.2 and Ti0.8B0.2Ni were synthesized by mechanical alloying and by milling with subsequent annealing. X-ray analysis of the as-milled alloys shows a broad diffraction peak, which position corresponds to the cubic TiNi. Annealin

Amorphous and nanocrystalline TiNi 1− x M x (M = Co, Fe, Sn; x = 0 and 0.2) alloys were synthesized by mechanical alloying. Powder particles with an average diameter of about 5 μm were produced. X-ray diffraction analysis showed that after 10.5 h
