With the continuous advancement of advanced materials research, scientists are increasingly focusing on the microstructural evolution of materials under complex temperature environments. Compared with traditional static testing methods, in-situ diffraction technology enables real-time observation of crystal structure, phase transition behavior, and stress evolution during heating, cooling, and other processes, providing more realistic and accurate data support for material development.
Recently, our company successfully delivered a synchrotron radiation in-situ heating and cooling stage to a client. This device is specifically designed and developed for synchrotron radiation in-situ diffraction experiments and is compatible with the in-situ experimental setup at the Shanghai Synchrotron Radiation Facility. It allows real-time in-situ X-ray diffraction measurements of samples throughout the entire temperature range from low to high temperatures, meeting the demand for dynamic tracking of material structural evolution.
Main Technical Features of the Device:
① Large opening angle design for improved diffraction data collection efficiency
To meet the specific requirements of synchrotron radiation in-situ diffraction experiments, the delivered heating and cooling stage adopts a large opening angle design, achieving a diffraction angle of up to 113.34°.
The large diffraction window effectively expands the detection range, allowing the detector to capture more diffraction information, thereby improving data collection efficiency and experimental sensitivity. At the same time, it provides a richer data foundation for phase structure analysis of complex material systems, helping researchers more comprehensively obtain structural evolution information during temperature changes.
② Customized holder design for optimized optical path matching
To further enhance compatibility with the synchrotron radiation light source system, our company designed a customized holder based on the customer's experimental requirements. By optimizing the device installation position and sample space layout, the X-rays emitted by the synchrotron radiation light source can fully cover the entire test sample area, thereby increasing the effective irradiation area and ensuring the completeness and consistency of experimental data.
At the same time, this design significantly reduces the difficulty of optical path focusing and position adjustment during on-site experiments, shortens debugging time, improves experimental efficiency, and provides users with a more convenient operating experience for continuous in-situ experiments.
③ Stable and reliable, meeting the needs of multi-scenario in-situ testing
This synchrotron radiation in-situ heating and cooling stage features excellent temperature control performance and structural stability, meeting the in-situ testing requirements of materials under heating, cooling, and constant temperature conditions.
The device is suitable for multiple research fields including metallic materials, ceramic materials, energy materials, semiconductor materials, and advanced composite materials. It can be widely used for:
• Study of material phase transition behavior
• Analysis of crystal structure evolution
• Thermal stability evaluation
• Residual stress and strain research
• New material development and performance optimization
• Development of metals and advanced ceramic materials
By combining precise temperature control technology with synchrotron radiation in-situ characterization techniques, the device helps researchers gain a deeper understanding of the relationship between the microstructure and macroscopic properties of materials.
