High-throughput preparation method and applications of material, and apparatus for high-throughput preparation of material

Abstract

The present invention provides a high-throughput preparation method of a material, wherein a material sample is heated, the heated material sample is subjected to thermal insulation, and the obtained material sample is maintained at the in situ state while cooling is performed on the obtained material sample from one end. According to the present invention, the material collections having different microstructures and properties are prepared in the high-throughput manner by cooling the material sample from one end, wherein the heat dissipating way of the cooling end is the direct heat exchange between the metal material and the cooling medium, such that the cooling rate is rapid; and the longitudinal surface of the material and the other end surface are subjected to relatively less heat dissipating, the sample is subjected to heat dissipating along the longitudinal direction mainly in the heat conduction manner so as to provide the slow cooling rate, and the cooling rate from the bottom portion to the top portion of the sample is gradually reduced, such that a series of different continuous cooling rates are achieved on the one sample so as to obtain the material collections having different microstructures and properties. The present invention further provides an apparatus for high-throughput preparation of a material, and applications of the material in high-throughput structure characterization and mechanical characterization.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a high-throughput preparation method of materials, its application and a device for high-throughput preparation of materials. Background technique [0002] The cooling rate of materials such as metal materials and ceramic materials during heat treatment will directly affect the microstructure of the material, and ultimately affect the mechanical properties of the material. Therefore, it is very important to study the cooling rate during the heat treatment of metal materials to optimize the heat treatment process and improve the mechanical properties of materials. [0003] At present, the main method for measuring the influence of different cooling rates on the structure and properties of materials is: to prepare samples for the same multiple samples at different cooling rates and to test the structures and properties of these samples respectively. Although this method can real...

Problems solved by technology

Although this method can realize the detection of the influence of different cooling rates on the structure and properties of materials, this scheme is restricted by many factors in the actual detection process, and it cannot guarantee that there is only a single variable of cooling rate, so the detection results cannot be guaranteed. the accuracy of

At the same time, the method requires a lot of materials, and the preparation and detection time is long, which causes the cost of the method to be high.

[0004] At present, the cooling methods in the heat treatment process of materials include: water quenching, oil quenching, and cooling in the air. The above cooling methods are all directly cooling the sample in the cooling medium, and the cooling rate is single or difficult to control.
