Description
Technical Field
The invention relates to the technical field of material science, in particular to an amorphous alloy material, an amorphous alloy structural member using the material and application.
Background
With the increase of software speed and hardware level, the existing consumer electronics products are continuously developing towards lighter, thinner and richer functions. The consumer electronics's volume constantly diminishes weight constantly and is becoming light still to carry on sensor, camera module, fingerprint collection device, screen and the battery that capacity is bigger and bigger of a great variety and quantity simultaneously. The above situation puts higher demands on the supporting material of the consumer electronic product, and not only needs to have light weight, but also needs to have higher strength to support a plurality of electronic components to be firmly installed on the supporting material, so as to play roles of fixing and protecting, and simultaneously, the supporting material can not shield the network and signals. For the new generation of foldable consumer electronic products, in order to control the overall thickness, the supporting and rotating shaft portions need to be lighter and thinner, so as to support and protect the electronic components mounted thereon without increasing the thickness of the main body. Particularly, the rotating shaft part needs to be subjected to high-frequency and large-amplitude rotation, and in order to ensure the using effect and the service life of a product, the material of the rotating shaft part needs to have high mechanical strength, hardness, wear resistance and low density.
At present, the strength of plastic materials can not meet the requirements, and high-strength materials such as ceramics and the like can not be produced in batch because of not having proper processability. Therefore, the attention of many manufacturers has been shifted to metal materials.
The metal material as a whole is more suitable for the current consumer electronics requirements than plastic and ceramic materials due to its higher specific strength. At present, two materials of aluminum alloy and stainless steel are widely used.
The density of the aluminum alloy is low, so that the overall quality of the product can be effectively reduced, the requirement of portability is met, but because the aluminum alloy has low indexes in the aspects of strength, hardness, wear resistance and the like, the shell and the support prepared from the aluminum alloy often face the risk of easy bending and deformation, and the interior of the product cannot be effectively supported and protected. Meanwhile, the electromagnetic shielding phenomenon is obvious, and the normal use of partial functions is influenced.
Stainless steel has higher strength, but has higher density, which can aggravate the overall quality of the product and reduce the use sense of consumers.
Meanwhile, the conventional material needs a plurality of processes to be repeatedly processed and molded in the processing process. Not only the processing cost is high, but also stress concentration exists in the processing process due to the characteristics of a crystal structure, a plurality of times of heat treatment is needed to eliminate residual stress, otherwise, deformation caused by residual stress release exists in a long stage in the process of assembling a product or using the product, the assembly or the use is influenced, and even more, the permanent damage of the product can be caused.
On the other hand, since the conventional material inevitably generates heat during the material removing process or the material additive process to cause warpage, there is a case where subsequent deformation occurs even by the heat treatment and the shaping. Therefore, the flatness requirement when the thin-wall part is manufactured is difficult to ensure, and the flatness requirement is shown in that the product cannot be assembled or the use is influenced by abrasion caused by the matching result.
The upper limit of material properties limits the evolution of consumer electronics towards lighter and thinner, for example, no foldable cellular phones have been available to date that can reach the level of mass production, just because the properties of conventional materials do not satisfy both the support and folding functions in a folded structure.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide an amorphous alloy material, an amorphous alloy structural part which has high specific strength, good wear resistance and elasticity and is not easy to generate plastic deformation is manufactured by the amorphous alloy material, the amorphous alloy structural part is suitable for a rotating shaft of a folding screen mobile phone and a structure matched with other parts through the rotating shaft, the amorphous alloy structural part has the characteristic of high strength and can effectively support the structure of the mobile phone which needs to be thinned due to unique design, particularly the structure is positioned at the key position of folding action, the amorphous alloy structural part can effectively support the folding screen, the folding action can be smoothly finished by the elasticity and the wear resistance of the amorphous alloy structural part, and the high flatness of the amorphous alloy structural part can ensure that the folding structure can not generate torsional warping during the action so as to realize smooth folding.
