The invention discloses a system and method for preparing an ultra-high vacuum electromagnetic suspension material, comprising: a cavity, a vacuum acquisition unit and a control system; wherein the devices associated with the cavity include a sample suspension mechanism, a sample transmission mechanism, an image acquisition unit, a sample Temperature monitoring mechanism, sample position detection mechanism, die casting unit and safety and accessory facilities. Based on the principle of electromagnetic induction, the present invention prepares large-volume metals and alloys under high-vacuum and container-free conditions, thereby obtaining more extensive and accurate basic thermophysical property data, and providing reliable original data for high-precision simulation calculations; through control The system can flexibly and effectively control the temperature and suspension state of the liquid metal in suspension. Combining with the image acquisition system, temperature monitoring mechanism and pressure casting system, it can carry out a wide range of high-temperature liquid metal solidification and deep subcooling experiments. It can directly shape the liquid metal in the deep supercooled state, and has excellent mechanical properties.

Description

technical field [0001] The invention relates to the technical field of material processing, and in particular to a system and method for preparing an ultra-high vacuum electromagnetic levitation material. Background technique [0002] The non-container processing technology uses the external physical field to balance the gravity of the sample, so that the object is in a suspended state, and at the same time uses a variety of non-contact detection methods to study the liquid properties and solidification principle of the material. Pneumatic levitation, ultrasonic levitation, electrostatic levitation and electromagnetic levitation are currently widely used containerless treatment methods. All of the above technologies can achieve stable suspension of particulate samples (sample diameters range from 1 to 6mm, weights range from 0.01 to 2g, materials range from polymers to various metals and alloys), and they play a prominent role in basic scientific research. However, limited ...
