Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to a zirconium-based amorphous alloy with high compression resistance and a preparation method thereof. Background technique [0002] Considering the atomic model of the constituent matter, matter can be divided into two types: ordered structure and disordered structure, among which crystals are typical ordered structures, while gaseous, liquid and some solids belong to disordered structures. Amorphous alloys, referred to as amorphous alloys, refer to metal alloys that do not have long-range order but have short-range order. Due to the characteristics of metal alloys, amorphous alloy liquids are called glassy alloys or amorphous alloys. Amorphous alloys have long-range disorder but short-range order, which means that the atoms do not exhibit periodic and translational symmetry in spatial arrangement, but the bonding with adjacent or sub-adjacent atoms has certain regularit...

AI Technical Summary

Problems solved by technology

Although the Zr-based amorphous alloys developed in the prior art have good formability and good processability, there are still some problems that cannot be ignored in the actual application process.

For example, when Zr-Cu-Ni-Al quaternary alloy is used as a replacement material for ordinary materials, its compressive performance is slightly worse than that of hard stainless steel. When used as a structural part that requires high compressive performance, the alloy material as a whole Soft, cannot replace hard stainless steel
