  • Patent number: 11890660
    Abstract: The present invention discloses a preparation method for a metal material, including: horizontally placing a to-be-prepared metal material between wavy surfaces of a female die and a male die; connecting a press machine with the male die; pressing the metal material through the male die, so that the metal material makes complete contact with the male die and the female die; ejecting the pressed metal material; horizontally overturning the metal material, and then placing the metal material between the wavy surfaces of the female die and the male die; repeatedly performing the pressing and overturning processes until accumulated strain of the metal material meets a requirement; and taking out the metal material after the deformed metal material is flattened by a plane die. According to the present invention, a large-size nano grained material can be manufactured.
