Technical Field

The invention relates to a processing technology of a zirconium-based amorphous product, in particular to a flatness leveling method for a zirconium-based amorphous thin-walled part.

Background

The zirconium-based amorphous alloy has high strength and good dimensional accuracy, and can be directly molded into a complex structure to obtain the favor of a structural design engineer; especially for ultra-thin structures. However, most amorphous superstructures are die-cast, and are affected by stress, processing heat and the like in the processes of mold stripping and post-processing, so that the flatness deformation phenomenon of products is easy to occur, and the use of the products is affected.

According to the traditional leveling method for the metal material product, the poor flatness is eliminated by using the product to deform under pressure, but due to the inherent characteristic of zirconium-based amorphous, the product only deforms elastically under the action of pressure, does not deform plastically, and cannot be shaped through pressure. By adopting the traditional hot-pressing shaping, the amorphous material can be subjected to plastic deformation at high temperature, but the crystallization of the zirconium-based amorphous product can be caused under the high-temperature environment and the cooling speed is too low, so that the performance of the material is changed, and the final use is influenced.
