The process of thermal stabilization of cold sintered amorphous powder of 82Ni18P was studied using the method of measuring the electrical resistance in non-isothermal and isothermal conditions. It was shown that the process of crystallization followed by further structural arrangement occurs in stages in the temperature interval from 623 to 723 K. By measuring the change in electrical resistance at constant temperatures, T1 = 613, T2 = 633 and T3 = 653 K, the kinetic parameters of the process of structural ordering of the evaluated substance were found. It was shown that every stage of crystallization is followed by a decrease in electrical resistance
