The present study focuses on investigating the evolution of phase transformations in Mg-Ni-Ce system under influence mechanical synthesis (MS) and spark plasma sintering (SPS). Magnesium powder mixtures with different nickel cerium contents (Mg-3%Ni-2%Ce, Mg-7%Ni-3%Ce, Mg-10%Ni-5%Ce) were mechanically activated along various grinding parameters. X-ray analysis (XRD) has shown successive stages formation MS process: from initial components to intermetallic compounds Mg2Ni, Mg12Ni6, CeMg3. An increase intensity treatment facilitated accelerated destruction crystal lattice, generation defects, new phases, as evidenced by broadening reduction Mg diffraction peaks. subsequent SPS stage promoted completion transformations, structural stabilization, a dense, multicomponent microstructure uniform distribution compounds. observed average crystallite sizes ranged 20 70 nm, depending processing conditions. research results demonstrate possibility targeted control over composition, opening opportunities for development highly efficient hydrogen-absorbing alloys.
