We have investigated the influence of annealing on the physicochemical properties of amorphous alloys based on aluminum. It has been established that, after annealing at the temperature of the first stage of crystallization, an X-ray amorphous structure with an insignificant volume fraction of a disordered nanocrystalline phase forms. In this case, the polarization resistance of the surface of the alloys in a 0.5 М aqueous solution of NaOH increases substantially, and the free potential shifts in the direction to anode potentials. In structural transformations under these conditions, the microhardness of the alloys increases to a maximum degree.
