Embodiment 1

[0033] Such as figure 1 As shown, the high-throughput preparation device suitable for Doka materials in this embodiment includes integrated computer-controlled multi-component screw feeder, centralized induction melting, array crucible matrix and multi-cooling rate array suction casting system and its subsidiary systems. The screw feeder, induction melting and suction casting system described therein are arranged from top to bottom, and can also be arranged horizontally or in other ways as required. If the screw feeder, induction melting and suction casting system are arranged up and down, the array crucible matrix is ​​movable up and down.

[0034] Taking La1+x Fe13Siy (x=0-1.2, y=1.1-1.8) as an example, replace the required La, Fe, and Si atomic ratios with volume fractions, and input the volume composition range of each element into the batching computer. The computer automatically calculates the volume of alloying elements required for each sample, and sends the informat...

Embodiment 2

[0040] Such as figure 1 As shown, the high-throughput preparation device suitable for Doka materials in this embodiment, wherein the induction melting is an upper and lower multi-layer induction melting system (such as Figure 4 Right), the suction casting system has two sets of corresponding suction casting molds and corresponding suction casting nozzles.

[0041] Taking Ni100-x-y-zFexGayCoz, where 17≤x≤26, 25≤y≤28, 0≤z≤6 as an example, the required atomic ratio of Ni, Fe, Ga, Co is replaced by volume fraction, and the volume of each The volume composition range of elements is input into the batching computer, and the computer automatically calculates the volume of alloying elements required for each sample, and sends the information to the designated screw feeder.

[0042] Add Ni, Fe, Ga, and Co alloy pellets to the four screw feeders respectively. According to the volume given by the batching computer, the screw feeder is automatically advanced to push the required volume o...

Abstract

The invention relates to a high-throughput preparation device and method applicable to duoka materials. The device comprises an integrated spiral feeding system, a centralized induction melting system, a vacuum suction casting system, a matching computer control system, a vacuum system and a cooling system. The preparation method comprises the technological process that alloy element powder or granules are added into a feeding hopper of a spiral feeder, a vacuum device is started, an alloy composition proportion is input into a computer, the alloy element addition amount is automatically calculated through the computer, the alloy element powder or granules are pushed into specified crucibles, the loading process of all the crucibles is completed, the crucibles ascend to the induction melting position, vacuum induction melting is carried out, a suction casting system descends, vacuum suction casting is carried out, and analysis is carried out. By means of the high-throughput preparation device and method, the novel duoka material development cost is reduced, the development process is simplified, and blocky duoka materials under multiple master batch and multiple solidification conditions are researched.

Description

technical field [0001] The invention relates to the field of preparation and processing of new functional materials, in particular to a high-throughput preparation device suitable for Doka materials and a preparation method thereof. Background technique [0002] The properties of a material are determined by the morphology and phase composition of the material, which are related to the composition and solidification conditions of the material. The traditional material development method obtains material performance-organization-composition-process information through a large number of trial and error experiments, which consumes a lot of manpower, material resources and development time. The industrialization process of a new material often requires decades of experimental research. This is especially true for Doka functional materials. Since the Doka functional material involves a complex phase transition process, it is a new type of energy-functional integrated material t...
