Embodiment 1

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

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

[0053] The first step, surface treatment: clean the surface of the iron foil and amorphous strip with a concentration of 3% hydrochloric acid alcohol to remove the oxide film on the surface of the foil. Afterwards, the iron foil and amorphous strips were polished with 240#, 400#, 800#, 1000#, 1500#, 2000# sandpaper to a bright surface, and then wool felt was used to grind the foil from the horizontal, vertical and 45° directions. Polish in the direction, and finally place it in an ultrasonic cleaning mach...

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 3D printing composite material preparation, in particular to a preparation method for manufacturing an amorphous / metal foil micro-laminated composite material using ultrasonic consolidation technology. Background technique [0002] Due to its special long-range disorder and short-range ordered atomic structure, amorphous alloys show more excellent properties than conventional crystalline metals, such as high strength, high modulus, good wear and corrosion resistance, and excellent magnetism Performance, etc., has a very broad application prospects in aviation, aerospace, military and civil fields. However, due to the poor plasticity of amorphous alloys at room temperature and the small critical size of bulk amorphous materials that can be prepared currently, the wide application of amorphous alloys is greatly restricted. Metallurgical welding between amorphous and metal foil at low temperature can be realized...
