Description

technical field [0001] The invention relates to the technical field of preparation of metal functional materials, in particular to a method for regulating the average atomic cluster size of an amorphous alloy. Background technique [0002] Unlike the case where organic liquids such as water are divided into anions and cations, alloys form some very small atomic clusters after melting. The atomic arrangement inside and on the surface of the atomic clusters is different from that of crystal materials, and changes with the size of the atomic clusters. In the case of a certain alloy composition, the size, geometry and characteristics of atomic clusters still show obvious differences with the difference of melt temperature. Amorphous alloys retain the atomic cluster structure characteristics of the melt, so atomic clusters are the basic units that constitute the electronic band structure of amorphous alloys. Crystalline materials have a periodically distributed electronic band s...

Problems solved by technology

Although the atomic cluster structure and size of amorphous alloys are closely related to the macroscopic properties of amorphous alloys and are the basis for realizing the macroscopic properties of amorphous alloys, the structure and size of atomic clusters in alloy melts are complex and diverse, and As the temperature of the melt changes, there is currently no experimental technique that can directly measure the atomic cluster structure and size of the amorphous solid alloy and the melt, and obtain information on the atomic cluster structure and size
