Embodiment 1

[0051] Example 1: Preparation of amorphous / iron foil micro-laminated composite material

[0052] This embodiment is a preparation method of an iron-based amorphous alloy / iron foil micro-laminated composite material, and the described amorphous alloy is made of Fe 73.5 Si 13.5 B 9.5 Cu 1 Nb 2.5 A strip with a width of 25 mm and a thickness of 30 μm is produced; the iron foil is T2 pure iron foil with a thickness of 150 mm×150 mm and a thickness of 650 μm. The concrete process of this embodiment is:

[0053] The first step, surface treatment: clean the surface of the iron foil and amorphous strip with 3% hydrochloric acid alcohol to remove the oxide film on the surface of the foil. Then, the iron foil and the amorphous strip were polished with 240#, 400#, 800#, 1000#, 1500#, 2000# sandpaper in sequence until the surface was bright, and then the foil was sanded horizontally, vertically and 45° with wool felt. Grind in the same direction, and finally place it in an ultrasoni...

Abstract

The invention relates to an ultrasonic accumulation preparation method for an amorphous / metal micro-laminated composite. The preparation method comprises the steps that laminating data of a part are extracted, amorphous / metal foil is welded onto a metal foil substrate layer by layer through the ultrasonic solidification technique, the welded amorphous / metal micro-laminated composite is cut layer by layer according to a set part contour, and finally the part composed of the amorphous / metal micro-laminated composite is obtained. By adoption of the method, manufacturing of the three-dimensional complex-shaped part composed of the amorphous / metal micro-laminated composite and manufacturing a large-size amorphous-matrix micro-laminated composite can be achieved easily. The micro-level multi-interface effect of the composite can overcome the disadvantages of poor indoor-temperature plasticity and low breaking tenacity of amorphous alloy, and low residual internal stress and good structural stability of the interior of the formed three-dimensional part can be guaranteed through the ultrasonic solidification technique.

Description

technical field [0001] The invention relates to the technical field of preparation of 3D printing composite materials, in particular to a preparation method for manufacturing amorphous / metal foil micro-laminated composite materials using ultrasonic consolidation technology. Background technique [0002] Due to its special atomic structure of long-range disorder and short-range order, amorphous alloys exhibit more excellent properties than conventional crystalline metals, such as high strength, high modulus, good wear resistance and corrosion resistance, and excellent magnetic properties. Performance, etc., have very broad application prospects in aviation, aerospace, military and civilian fields. However, due to the poor room temperature plasticity of amorphous alloys and the small critical size of bulk amorphous materials currently available, the wide application of amorphous alloys is greatly limited. The metallurgical welding between amorphous and metal foils at low temp...
