The work presents research results of Ni in different structural states. The sample was subjected to severe plas-tic deformation on Bridgman anvils under pressure of 7 GPa at deformation e=7 and following annealing at differ-ent temperatures in the range from 150 0C to 500 0C. The investigations of sample structure, microhardness and elec-tro resistivity in different structural state are shown. Ab-normal growth the nanocrystalline nickel microhardness after annealing at different temperature is discussed.
