System and method for preparation of ultrahigh vacuum electromagnetic suspension material

Abstract

The invention discloses a system and method for preparation of an ultrahigh vacuum electromagnetic suspension material. The system comprises a cavity, a vacuum acquisition unit and a control system, wherein devices associated with the cavity include a sample suspension mechanism, a sample transmission mechanism, an image collection unit, a sample temperature monitoring mechanism, a sample position detection mechanism, a pressure casting unit and safety and accessory facilities. The system and method disclosed by the invention have the beneficial effects that metal and alloy with large volumes are prepared under a high-vacuum and container-free condition based on principles of electromagnetic induction, so more extensive and accurate data of basic thermal physical natures is obtained, and reliable original data can be provided for high-precision simulation computation; by the control system, temperatures and suspension states of the liquid metal at a suspended state can be controlled flexibly and effectively; and in combination with an image collection system, the temperature monitoring mechanism and a pressure casting system, extensive experimental research on high-temperature liquid metal solidification and high overcooling can be carried out, and the liquid metal can be directly shaped under a highly overcooled 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 ...
