Definitions
- the present invention is a.
- the invention belongs to the field of amorphous alloy thermoplastic forming, and more particularly relates to a plastic forming and gradient toughening method and a device based on ultrasonic vibration.
- Amorphous alloy is a novel material with excellent properties such as high strength, corrosion resistance and wear resistance. Amorphous alloy exhibits good superplasticity in the hot state and can achieve near net shape formation of parts. However, due to the significant room temperature brittleness of the amorphous alloy, the amorphous alloy parts may directly undergo brittle fracture and completely fail once they are overloaded during service, making it difficult to directly apply the amorphous alloy parts in occasions where impact loads are present. Therefore, it is necessary to further improve the toughness of the amorphous alloy without impairing its excellent properties so as to improve the impact resistance of the amorphous alloy parts.
- the amorphous alloy is in a thermodynamically metastable state, and spontaneously transformed to its thermodynamically stable state after obtaining sufficient energy, that is, crystallization occurs. After the amorphous alloy is crystallized, its properties are also changed. By forming nanocrystallines inside the amorphous alloy, the strength and toughness of the amorphous alloy can be remarkably improved. Therefore, according to the requirements of actual service conditions for the performance of amorphous alloy parts, nanocrystallines can be induced locally in the amorphous matrix by some means to form a nanocrystalline toughened amorphous matrix composite with a mechanical property gradient.
- Chinese Patent Publication No. 101736213 proposed a method for strengthening and toughening an amorphous alloy by ultrasonic treatment, in which the amorphous alloy is strengthened and toughened by placing the amorphous alloy in a cooling water tank with a temperature lower than the crystallization temperature of the amorphous alloy and then applying an oscillation frequency with a power less than 3 ⁇ 10 4 W/mm 2 per unit area at the bottom of the water tank.
- the amorphous alloy treated by the method has a great improvement in plastic deformation capability at room temperature and an increase in thermal discharge in relaxation, with the precondition that the fracture strength is not changed.
- Cispheral Patent Publication CN 101698903 A discloses a method for preparing a metal matrix amorphous/nanocrystalline composite layer, comprising the steps: preparing metal matrix amorphous solid or preparing a metal matrix amorphous coating on the surface of an object by a conventional method; putting the prepared metal matrix amorphous solid or the object with the metal matrix amorphous coating into water, at room temperature and under ultrasonic environment, vibrate at a frequency between 6.0 and 30.0kHz with an ultrasonic transducer to act on the metal, ultrasonic power between 100 and 500W, and forming the amorphous/nanocrystalline composite layer on the metal piece or the surface of the object.
- Chinese Patent Publication No. 102002659 proposed a method for continuously performing nanocrystallization on an amorphous alloy strip, in which at a temperature below the glass transition temperature of the amorphous alloy, the amorphous alloy strip is pressed on the top end of an amplitude transformer of a power ultrasonic device, and the amplitude transformer of the ultrasonic device exerts an ultrasonic effect on the amorphous alloy strip as the amorphous alloy strip moves, thereby achieving continuous nanocrystallization of the amorphous alloy strip.
- this method can only process the entire amorphous alloy strip, and can neither process actual parts with complex shapes nor achieve nanocrystal gradient toughening; Chinese Patent Publication No.
- 105420522 proposed a method for preparing an amorphous matrix composite, in which the flaky amorphous alloy and the second phase toughening material are alternately laminated and placed in a jig, and under a condition of constant pressure or increasing load, the laminated amorphous alloy and porous plate are heated while ultrasonic vibration is applied thereto, so that the amorphous alloy is rapidly softened and pressed into the pores of the second phase toughening plate to obtain an amorphous matrix composite.
- this method needs to introduce a second phase to perform overall toughening treatment on the amorphous alloy, is only suitable for the processing of sheet products, and cannot enable the processing of actual parts with complex shapes as well as local nanocrystalline gradient toughening of the parts according to actual use requirements.
- the present invention provides a plastic forming and gradient toughening method and a device based on ultrasonic vibration, which aims to achieve nanocrystallization of a local region to be toughened on the amorphous alloy part by applying ultrasonic vibration to the local region to be toughened with an insert connected to an ultrasonic vibration amplitude transformer, thereby solving the technical problem of local toughening during thermoplastic forming.
- a plastic forming and gradient toughening method based on ultrasonic vibration characterized in that the toughening method comprising:
- the forming temperature is between a glass transition temperature and a crystallization temperature of the raw material blank.
- the toughening device is preferably a mold for thermoplastic forming.
- the material of the amorphous alloy part is a Pd, Pt, Au, Zr, Ti, Fe, Cu, Ni, Al, Mg or Ce based amorphous alloy with a thermoplastic forming ability.
- a device for use in the above toughening method characterized in that the device comprises an upper mold, a lower mold and a female mold, the upper mold and the lower mold are oppositely disposed and form a mold cavity with the female mold, the upper mold and the lower mold are respectively provided with a punch and more than one inserts, the punches are connected to a driving servo press and used to form raw material blank into a desired three-dimensional structure, the inserts are connected to an ultrasonic vibration amplitude transformer and used to apply ultrasonic vibration to one or more portions to be toughened, the female mold is provided with one or more resistance heating rods for heating the raw material blank.

- the ultrasonic vibration is stopped, and the upper mold is moved up to be separated from the part.
