Shock compression loading recycling box and method for preparing material by shock compression

Abstract

The invention discloses a shock compression loading recycling box and a method for preparing material by shock compression. The shock compression loading recycling box comprises a pedestal and a spiral cover, wherein the surface of the pedestal is inwards depressed to form a sample bin, and the spiral cover is arranged in the sample bin and is detachably connected with the pedestal. The method for preparing the material by the shock compression comprises the following steps of pre-pressing the sample powder into a tablet; putting the tablet into the sample bin of the pedestal, tightening the spiral cover, attaching the tablet and the bottom part of the sample bin, putting the recycling box into a steel frame, and aligning the bottom part of the pedestal and the center of a gun opening of a light-gas gun; using the light-gas gun to drive a fly sheet to impact the pedestal, so as to prepare a sample; using a machine tool to fetch the sample out of the recycling box, and sanding off the impurities at the surface of the sample, so as to obtain the sample. The shock compression loading recycling box has the advantages that the structure is simple, and the manufacturing is convenient; in combination with a magnetic speed tester on the light gas gun, the other complicated accessories are not needed, and the installation and the preparation of the shock compression sample are convenient.

Description

technical field [0001] The invention belongs to the technical field of impact compression loading, and in particular relates to an impact compression loading recovery box and a method for preparing materials through impact compression. Background technique [0002] With the development of high technology, materials have become the three pillars of modern science and technology alongside energy and information. Under the action of pressure and temperature, the properties of materials may change strangely. For example, graphite can be transformed into diamond through phase transition under high temperature and high pressure, and it can remain stable after the pressure is released. This provides us with the opportunity to find materials that can exist for a long time under extreme conditions The metastable phase provides the basis. The electronic structure and magnetic properties of superconducting materials can be tuned by pressure; the pressure-induced change from soft to ha...

AI Technical Summary

Problems solved by technology

Many recovery devices will add some speed measuring or sensing devices to measure the impact speed as accurately as possible, but the added measuring tools will cause a certain error between the measured value and the actual value

There is also soft recovery technology, in order to better obtain samples, a buffer material to accommodate Doppler optical fiber signals is placed in the recovery device, and there are many buffer layers, which will make the calculation process of temperature and pressure too complicated

In addition, the recovery device of the chemical explosion method using the detonator in the early stage adopted a rectangular structure, which made the production of the recovery device relatively troublesome
