preparation example Construction

[0028] Preparation method of the present invention:

[0029] The first is the pretreatment of Al1100 and TA1 metal strips:

[0030] (1) Cut Al1100 and TA1 strips with a length and width of 800mm×24.5mm and a thickness of 200μm;

[0031] (2) Place the cut metal strip in an ultrasonic cleaner and clean it with alcohol for 15-20 minutes.

[0032] Secondly, stack them in the order of "Ti strip-Al strip", and finally prepare Ti / Al prefabricated strips by using ultrasonic consolidation rapid prototyping equipment;

[0033] Finally, the Ti / Al prefabricated strip prepared by ultrasonic consolidation rapid prototyping was peeled off from the substrate, and placed in a vacuum hot-press furnace for sintering to prepare a Ti / Al3Ti layered composite material. The test principle and flow chart are shown in the appendix. figure 1 .

[0034] Main process parameters:

[0035] Ultrasonic consolidation rapid prototyping parameters: substrate preheating temperature 150 ℃ ~ 200 ℃, ultrasonic c...

Abstract

The invention provides a rapid preparation method of a composite material Ti / Al3Ti based on ultrasonic consolidation forming as supplementary means. The method comprises putting a cut Al band and a cut Ti band in an ultrasonic cleaner, washing the bands through alcohol for 15-20min, alternately and orderly stacking the Al band and the Ti band in an order of Al band-Ti band, preparing a Ti / Al prefabricated band through an ultrasonic consolidation fast formation device, separating the Ti / Al prefabricated band obtained by the ultrasonic consolidation forming from a base plate, putting the Ti / Al prefabricated band in a vacuum hot press furnace and carrying out hot press sintering to obtain the layered composite material Ti / Al3Ti. The rapid preparation method solves the problem that the traditional metal foil metallurgy technology for preparing the layered composite material Ti / Al3Ti has a slow reaction rate and a long preparation period, and provides a novel technological approach for further industrialization of the composite material Ti / Al3Ti.

Description

technical field [0001] The invention relates to a preparation method of a composite material, in particular to a Ti / Al 3 Rapid preparation method of Ti composites. Background technique [0002] In recent years, Ultrasonic Additive Manufacturing (UAM) technology developed on the basis of metal ultrasonic consolidation (Ultrasonic Consolidation, UC) forming technology has attracted widespread attention at home and abroad. UAM technology uses high-power ultrasonic energy, uses metal foil as the raw material, and uses the heat generated by the vibration and friction of the metal layer to make the material locally undergo severe plastic deformation, thereby achieving physical metallurgical bonding between atoms, and realizing the same or different metals A special method of solid-state bonding between materials. Compared with the existing high-energy three-beam (laser, particle beam and plasma beam) additive rapid prototyping and manufacturing technology, UAM technology has the...
