Definitions
- the present disclosure relates to a Zr-based amorphous alloy and a preparing method thereof.
- Amorphous metallic alloys are disordered in the long range but ordered in the short range. They have desirable physical and chemical properties, such as high strength, high hardness, high wearing resistance, high corrosion resistance, relatively wide elastic range, high electric resistance, good superconductivity, and low magnetic loss. Amorphous metallic alloys have huge potential when used as structural materials. They are widely used in many fields such as mechanics, IT electronics, the military industry and so on.
- amorphous metallic alloys limit their applications. For example, it is difficult to manufacture large size amorphous alloys. To obtain the disordered structure in the long range, atoms' spontaneous movement in the freezing process shall be restrained. The higher the cooling speed is, the lower the possibility is for the atoms to form orderly arrayed crystalline materials via spontaneous movement. But as product size increases, the internal cooling speed within the product is declining. Thus, the internal amorphous degree is low in the long range and it is difficult to form large size amorphous structures.
- the amorphous alloy materials Due to their particular structure, while under stress, the amorphous alloy materials do not have the internal deformation mechanism as crystalline materials do in order to resist deformation. So when the stress reaches a certain degree, the amorphous alloy material may break suddenly, which may lead to catastrophic accidents. Thus, the applications of the amorphous alloy materials as structural materials are limited.
