Description

Technical Field

[0001] The utility model relates to the field of metallurgy, in particular to a quenching device for high-temperature powder samples. Background Art

[0002] The study of high-temperature physical properties is an emerging research direction in materials science today. It involves aspects such as the molecular structure, crystal structure and phase changes of materials. Under high temperature conditions, materials will undergo a series of changes. Studying these changes can enable us to better understand the relationship between the microscopic structure and macroscopic properties of materials, thereby developing more advanced materials for application in various fields.

[0003] However, high temperature conditions limit the choice of characterization methods, especially the characterization of phase changes, because when the material sample is slowly cooled in the air, the internal elements will recombine to form a new phase, resulting in changes in the subsequent phase characterization, which cannot accurately reflect the state of the phase in the material at high temperature. By consulting the literature, there are two main conventional practices: one is to use the characterization data of the sample after slow cooling to replace the performance of the material sample at high temperature. This method is relatively simple to operate and easy to implement, but the disadvantage is that the result accuracy is poor or no result; the other method is to quickly cool the high-temperature sample (quenching), and perform physical and chemical tests on the quenched sample. The test results after quenching can basically reflect the state of the material at high temperature. The disadvantage is that although there are many types of quenching devices in China, they are highly targeted. There is no quenching device suitable for all materials, especially quenching devices for high-temperature powder samples.

[0004] Therefore, it is necessary to provide a quenching device for high-temperature powder samples in the metallurgical field. Utility Model Content
