1. a preparation method for nano twin crystal Cu-Al or Cu-Zn alloy, comprises the steps:

  • (1) solution treatment is carried out to Cu-Al or Cu-Zn alloy;

    (2) the first stove of Cu-Al or Cu-Zn alloy during solution treatment is cold, then carries out brine refrigeration;

    (3) Cu-Al or the Cu-Zn alloy after brine refrigeration is soaked in liquid nitrogen, make the temperature of alloy identical with liquid nitrogen temperature;

    (4) rapidly channel deformation is carried out etc. to Cu-Al or Cu-Zn alloy;

    (5) Cu-Al or the Cu-Zn alloy after reciprocity channel deformation carries out sub-zero treatment.
