Abstract
Have been investigated the influence of annealing on the physicochemical properties of amorphous alloys based on aluminum. It has been established that: after annealing during 5, 15, 30, 45, 60 min at the temperature of the third stage of crystallization, an X-ray amorphous structure with an insignificant volume fraction of a disordered nanocrystalline phase forms. The temperature of annealing was determined from DSC-curves. In structural transformations under these conditions, the microhardness of the alloys increases to a maximum degree in these conditions. The optimal time limits of time heat treatment to improve the physicochemical properties of aluminum-based AMAs have been established.
