High throughput preparation device for metal fibers based on multiple powder and method of preparing metal fibers by means of same

Abstract

The invention relates to a high throughput preparation device for metal fibers based on multiple powder and a method of preparing the metal fibers by means of the same. The high throughput preparationdevice comprises a metal powder conveying system, a metal powder mixing system, a metal powder smelting system and a metal fiber forming system connected successively, wherein the metal powder smelting system comprises an inductive powder smelting device and a laser powder smelting device which are arranged independently. The high throughput preparation device has the characteristics of being simple in structure, convenient to operate, wide in smelting temperature and wide in application range. The method of preparing the metal fibers by means of the high throughput preparation device comprises four steps: powder transporting, powder mixing, smelting and forming. The metal fibers, components of which are changed in gradient continuously, can be prepared by means of the preparation method,and high throughput preparation is achieved.

Description

technical field [0001] The invention relates to the field of metal fiber preparation and processing, in particular to a multi-powder-based high-throughput metal fiber preparation device and a method for preparing metal fibers using the same. Background technique [0002] Structural materials are based on mechanical properties and are used to manufacture materials used in stressed components. Metal structural materials such as high-performance alloys and steel materials are widely used in the preparation of high-end equipment and components related to the national economy and people's livelihood, such as aero-engines, gas turbines for power generation, steam turbines, high-speed rail and automobiles, due to their excellent mechanical properties. With the rapid development of science and technology, the research and development of metal structural materials with better performance is becoming more and more urgent. However, in the traditional R&D method of metallic structural ...

However, this method still produces bulk material samples, which still have the disadvantages of high cost, low continuity, and the inability to continuously change the composition of bulk materials.

CN107502765A discloses a high-throughput micro-manufacturing method for multi-component materials. Using microwave energy field heating can realize high-throughput sintering and melting preparation or heat treatment of materials under different temperature gradient fields or the same temperature gradient field at one time. Although the The method prepares a smaller-sized bulk material sample, but limited by the number of sample slots in the array crucible used by the method, there are still shortcomings of low continuity and difficult gradient changes in the composition of the bulk material

[0005] Although the prior art disclosed above has developed a method for preparing metal structural materials, it is limited by bulk material samples and has not really solved the high-throughput problems of high cost, low continuity, and difficult gradient changes in bulk material composition.
