Embodiment 1

[0040] 20μm thick CrCoNi medium entropy alloy foil prepared by cryogenic asynchronous rolling, reference figure 1 ,Proceed as follows:

[0041] The first step: using pure aluminum foil material 1 as raw material, the thickness of pure aluminum foil material 1 before rolling is 200 μm. The thickness of the superhard metal foil 2 is 100 μm, and the middle entropy alloy CrCoNi foil is selected.

[0042] Step 2: The pure aluminum foil material 1 and the superhard metal foil material 2 are cut into rectangular sizes, the pure aluminum foil material 1 has the same width as the superhard metal foil material 2, and its length is doubled.

[0043] Step 3: Fold the pure aluminum foil material 1 in half, completely cover the superhard metal foil material 2, and obtain the stacked aluminum / ultra-high-strength metal / aluminum material 4. In order to prevent plastic bonding during the rolling process, the surface of the superhard metal foil 2 is coated with low temperature resistant lubric...

Embodiment 2

[0052] Preparation of 15 μm thick CoCrFeNiMn high-entropy alloy foil by cryogenic asynchronous rolling, reference figure 1 ,Proceed as follows:

[0053] The first step: using pure aluminum foil material 1 as raw material, the thickness of pure aluminum foil material 1 before rolling is 300 μm. The thickness of the superhard metal foil 2 is 200 μm, and the high-entropy alloy CoCrFeNiMn foil is selected.

[0054] Step 2: The pure aluminum foil material 1 and the superhard metal foil material 2 are cut into rectangular sizes, the pure aluminum foil material 1 has the same width as the superhard metal foil material 2, and its length is doubled.

[0055] Step 3: Fold the pure aluminum foil material 1 in half, completely cover the superhard metal foil material 2, and obtain the stacked aluminum / ultra-high-strength metal / aluminum material 4. In order to prevent plastic bonding during the rolling process, the surface of the superhard metal foil 2 is coated with low temperature resis...

Abstract

The invention provides a copious cooling asymmetrical rolling process for preparing metal foil material with ultra high strength. The copious cooling asymmetrical rolling process for preparing the metal foil material with the ultra high strength comprises the steps that a pure aluminum foil material and a super hard metal foil material are used as raw materials, the pure aluminum foil material isfolded, and the super hard metal foil material is wrapped completely and put into a copious cooling box for cooling; a cooled composite foil material is taken out for copious cooling asymmetrical rolling; a belt material after rolling is put into the copious cooling box for recooling; copious cooling box for cooling is further carried out on the cooled belt material; repetition is carried out for6-10 times to obtain a layered aluminum / ultra hard metal / aluminum duplex mental composite foil material; and the layered aluminum / ultra hard metal / aluminum duplex mental composite foil material is heated, a lubricating layer is softened, stripping is carried out on an aluminum layer and an ultra hard metal layer, the ultra hard metal foil material is taken out, that is the prepared metal foil material with the ultra high strength, such as a medium entropy alloy foil material, a high entropy alloy foil material, a special steel foil material and the like, the metal foil material has the ultrahigh strength and can avoid crack defects of rollers.

Description

technical field [0001] The invention belongs to the technical field of metal material rolling, and in particular relates to a cryogenic asynchronous rolling process for preparing ultra-high-strength metal foil. Background technique [0002] At present, ultra-high-strength metal foils have received more and more attention. For many metallic materials, the price rises exponentially as the foil thickness decreases. The main reason is that the thickness of the foil is reduced, and its processing difficulty is greatly increased. [0003] At the same time, during the rolling process of some difficult-to-deform metal foil materials, when the deformation resistance and hardness of the rolled piece far exceed the hardness of the roll, the roll may be cracked during the rolling process, resulting in processing accidents and causing serious damage to the enterprise. Big loss. Contents of the invention [0004] In order to overcome the shortcomings of the above-mentioned prior art,...
