Background

Amorphous alloys, referred to as amorphous alloys for short, are amorphous solids obtained by heating a metallic material to a molten state and then rapidly cooling it. Compared with the traditional crystalline metal material, the amorphous alloy shows a plurality of unique physical, chemical and mechanical properties such as high strength, high elastic limit, wear resistance, corrosion resistance and the like and good thermoplasticity due to disordered atomic arrangement in the amorphous alloy. Although amorphous alloys have many excellent properties, the use of amorphous alloys in structural engineering is severely limited due to the small critical dimension that can be produced from amorphous alloys.

Aiming at the problem of small critical dimension of the amorphous alloy, the most effective method is to search the amorphous alloy material with strong glass forming capability or prepare the amorphous alloy by adopting a faster cooling rate. However, only a few empirical criteria are currently followed to find an alloy system with a high glass forming ability, and the process requires a lot of manpower and material resources. In addition, the amorphous alloy prepared by adopting a faster cooling rate also needs expensive equipment and a complex preparation flow, and the preparation cost is greatly increased. The maximum size of the 'large-size amorphous alloy' which can be prepared up to now is only ten centimeters, and only one dimension can reach the size, so that the requirement in the actual structural engineering can not be met. Another method is to prepare large-size amorphous alloy by welding technology. However, there are still some outstanding problems in the welding process, such as: welding seam crystallization influences the mechanical property of the joint; superplasticity in the supercooled liquid region affects successful welding of amorphous alloys. In recent years, additive manufacturing technology has provided a possibility for the preparation of large-size, complex amorphous alloy components. However, the existing 3D printed amorphous alloy member has many disadvantages, such as: the crystallization phase is difficult to avoid; the composition is not uniform; the inside has defects; additional processing is still required subsequently. In general, the prior art still cannot break through the size limit of the amorphous alloy and realize the preparation of complex amorphous alloy components.
