Embodiment 1

[0034] A method for preparing a micro-laminated composite material by using ultrasonic material addition and hot isostatic pressing, the steps are:

[0035] (1) Surface treatment of TA1 titanium foil and 1060 aluminum foil with a thickness of 100um: the specific process is to first clean the two metal foils with hydrochloric acid alcohol with a mass concentration of 3%, and then use sandpaper to roughly grind the surface, and then place Clean in an ultrasonic cleaner, and finally wipe the surface of the foil with cotton dipped in acetone until it is thoroughly cleaned, then dry the surface with a hair dryer.

[0036] (2) First fix a layer of 1060 aluminum foil on the preheated aluminum substrate (100°C), then place a layer of TA1 titanium foil, and then use an ultrasonic generator to roll on the surface of the titanium foil, so that the titanium foil and aluminum foil are under rolling pressure And the welding is realized under the action of ultrasonic vibration; the static pr...

Abstract

The invention belongs to the technical field of preparation of micro-laminated composite materials, and particularly relates to a method for preparing a micro-laminated composite material by using ultrasonic additive and hot isostatic pressing and application thereof. The method comprises the following steps that (1) a first metal layer is fixed on a preheated substrate, then a second metal layeris placed on the first metal layer, and after the second metal layer is placed on the first metal layer, an ultrasonic generator rolls on the surface of the second metal layer, so that the first metallayer and the second metal layer are welded under the action of rolling pressure and ultrasonic vibration; and (2) the laminated material obtained in the step (1) is subjected to hot isostatic pressing heat preservation treatment, and then the micro-laminated composite material is obtained. According to the method, the low-temperature forming characteristic of ultrasonic welding is utilized, so that metal atoms are diffused on the contact interface between the metal layers through the action of vibration, friction and the like, and solid-state metallurgical bonding is realized; and the hot isostatic pressing technology is adopted to apply pressure to the upper surface and the lower surface of the laminated composite material, so that the preparation of the micro-laminated composite material with high density, good uniformity and excellent performance is realized.

Description

technical field [0001] The invention belongs to the technical field of preparation of micro-laminated composite materials, and in particular relates to a method for preparing micro-laminated composite materials by using ultrasonic material addition and hot isostatic pressing and its application. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] Micro-laminated composite materials are mainly composed of multi-layer micron-scale materials, with multiple interfaces, and the distance between the interfaces of each layer is very small. Under the joint action of multiple interfaces and small layer spacing, the comprehensive The performance is much higher than that o...
