Embodiment Construction

[0021] When the crystal absorbs heat from the outside, the average kinetic energy of the internal molecules and atoms increases, and the temperature also begins to rise, but the spatial lattice is not destroyed, and the regular arrangement is still maintained. Continue to absorb heat and reach a certain temperature—the melting point, the intensity of its atomic movement can destroy its regular arrangement, and the spatial lattice also begins to disintegrate, so the crystal begins to become a liquid. During the transformation process of the crystal from solid to liquid, the absorbed heat is used to destroy the space lattice of the crystal part by part, so the temperature of the solid-liquid mixture does not rise. When the crystal is completely melted, the temperature begins to rise again as it absorbs heat from the outside world.

[0022] Due to the irregular arrangement of molecules and atoms, amorphous does not need to destroy its spatial lattice after absorbing heat, but onl...

Abstract

The invention provides a device for preparing a high-precision metal amorphous tube, comprising an upper die (202) and a lower die (201), wherein, the upper die and the lower die form a die cavity (203) after being closed; the die cavity (203) is provided with a diameter enlarging part (204) and positioning parts (206) arranged at two sides of the diameter enlarging (204); and the diameter of thediameter enlarging part (204) is equal to the outer diameter of the high-precision metal amorphous tube to be prepared within a precision range, and the diameter of the positioning parts (206) is equal to the target inner diameter of the high-precision metal amorphous tube to be prepared within the precision range. The invention also relates to a preparation method of the high-precision metal amorphous tube.

Description

technical field [0001] The invention relates to a high-precision metal amorphous transistor manufacturing equipment and method. Background technique [0002] Amorphous refers to a solid in which the molecules (or atoms, ions) that make up the substance are not regularly arranged in space. It does not have a certain regular shape, such as glass, rosin, paraffin and so on. Its physical properties are the same in all directions, called "isotropy". It has no fixed melting point. So some people call the amorphous "supercooled liquid" or "little fluid liquid". [0003] Amorphous solids include amorphous dielectrics, amorphous semiconductors, and amorphous metals. They have special physical and chemical properties. For example, metallic glass (amorphous metal) has higher strength, better elasticity, higher hardness and toughness, better corrosion resistance, stronger magnetic permeability, and higher resistivity than ordinary (crystalline) metals. This makes amorphous solids ...
