Progress in Research on Preparation, Properties and Application of Al-based Amorphous Alloys

Aluminum-based amorphous alloys have a wide application prospect in many fields because of their unique physical and chemical properties. The composition system, preparation methods, properties and application of aluminum-based amorphous alloys were reviewed in this paper. First of all, the development history and composition system of aluminum-based amorphous alloys were introduced. At present, aluminum-based amorphous alloys can be divided into three major systems of binary, ternary and multicomponent systems, and two aspects of comprehensive properties and forming ability. At present, the aluminum-based amorphous system is mainly more than ternary system, gradually developing to multicomponent system. Secondly, the preparation methods of aluminum-based amorphous alloys were systematically introduced, including the preparation of powder, thin ribbon and bulk samples. Compared with the preparation of amorphous ribbons, the preparation methods of bulk and powder are more abundant. Powdered amorphous is usually used as the prefabricated material of aluminum-based amorphous coating. Then, the performance characteristics, application status and development trend of aluminum-based amorphous alloy were introduced in detail. From the point of view of properties, aluminum-based amorphous alloy performs well in strength, hardness and corrosion resistance. At present, it is mainly used in the form of coating. There are also some applications as functional materials by using the magnetic and thermoplastic properties of aluminum amorphous alloys, but due to the limitation of glass forming ability, they are rarely used as structural materials. Finally, the prospect of its application in the future was prospected. It is considered that the coating is the most promising engineering method for aluminum-based amorphous alloys at present.
