Scanning electron microscopy high-temperature in-situ systemIt is a scientific research instrument that combines a scanning electron microscope (SEM) with a high-temperature heating device, which can perform in-situ mechanical property testing and microstructure observation of materials in high-temperature environments.

System composition:

Scanning electron microscope body: equipped with high-resolution electron detectors such as secondary electron and backscattered electron detectors, which can provide surface sensitive high-resolution images for observing the microstructure of samples.

High temperature in-situ stage: It is the core component of the system, usually using resistance heating method, which can achieve precise control within a certain temperature range.

Control system: including temperature controller, mechanical controller, and corresponding software, which can achieve precise control and real-time monitoring of temperature, mechanical loading and other conditions.

Analysis attachment: It can integrate analysis tools such as energy dispersive spectroscopy (EDS) and electron backscatter diffraction (EBSD) to observe the morphology of the sample while conducting elemental analysis and crystallographic feature analysis.

Working Principle:

By scanning the surface of the sample with an electron beam using a scanning electron microscope, signals such as secondary electrons and backscattered electrons are generated for imaging purposes. At the same time, the high-temperature in-situ stage heats the sample to the set temperature, and under the condition of maintaining a vacuum environment, the microstructure changes of the sample at high temperature are observed in real time. Combined with attachments such as EDS and EBSD, the chemical composition, crystal orientation and other information of the sample are analyzed.
