I. Technical Principle

Visualized high-temperature deformation analysis technology employs optical non-contact measurement to quantify material deformation during the sintering process. By integrating high-temperature optical imaging, high-temperature heat treatment, and an intelligent image-processing system, this approach enables real-time, online monitoring of changes in material shape, dimensions, and phase state throughout temperature cycling. The system delivers intuitive, accurate data and graphical reports, allowing for the calculation of critical parameters such as thermal expansion, contraction, and characteristic temperature points.

II. Technical Features

1. Real-Time Capability: The use of optically visualized graphical analysis enables real-time observation of the deformation behavior of samples under high-temperature conditions, providing researchers with timely experimental data. Compared with the conventional “blind firing” method, this visualized sintering approach is more time- and labor-efficient, delivering twice the results with half the effort.

2. Accuracy: By integrating intelligent image processing and data analysis systems, the solution delivers intuitive and accurate data and graphical reports.

3. Versatility: Non-destructive testing is possible for shape deformation during sintering, regardless of whether the samples are regular or irregular in shape, fragile, or foamy.

4. Multi-dimensional analysis: Enables synchronous multi-dimensional analysis of changes in height, width, and area, making it particularly well-suited for testing non-proportional and irregular samples.

5. Multifunctionality: In addition to observing deformation, it can also analyze dimensional changes in the sample, calculate linear and volumetric shrinkage rates, sintering density, and the coefficient of thermal expansion, among other parameters. It can further be used to characterize characteristic temperature points such as the sintering onset and softening points, thereby providing a comprehensive understanding of the thermophysical properties involved in the material’s sintering process.

III. Research and Applications in the Ceramic Field

1. Optimization of the sintering process: Visualized high-temperature deformation technology enables real-time monitoring of ceramic material deformation during high-temperature sintering, allowing for the calculation of parameters such as shrinkage rate, densification, and apparent activation energy. This information can be used to optimize sintering parameters—including sintering temperature, dwell time, and heating rate—to achieve optimal sintering results, reduce production costs, and improve product quality.

2. Research and development of new ceramic materials: During the R&D process, these methods can be used to evaluate key performance indicators such as thermal stability, volumetric shrinkage, and relative density, thereby providing experimental evidence for optimizing material formulations and determining the optimal processing parameters.

3. Investigation of high-temperature wettability between ceramic materials and low-melting-point melts: This involves observing the high-temperature wetting behavior and in-situ melt infiltration between the melt and solid ceramic substrates, thereby gaining a deeper understanding of the underlying reaction mechanisms of melting, wetting, and melt infiltration. Such insights can then be leveraged to optimize formulations or process conditions for enhanced performance. This approach is particularly well suited for the research and development of thermal barrier coatings, environmental barrier coatings, and functional coatings.

IV. Research and Applications in the Field of Refractory Materials

1. Research on the slag resistance of refractories: Under conditions of high-temperature molten slag, refractory degradation is often the result of the combined effects of chemical erosion, mechanical action, and thermal stress; therefore, it is necessary to enhance the refractories’ thermal shock resistance and slag resistance. By employing visualized high-temperature deformation testing techniques, it is possible to investigate the wetting and penetration behaviors of high-temperature molten slag in refractory systems, thereby enabling optimization of refractory formulations and improvement of thermal shock resistance and slag resistance.

2. High-Temperature Stability Assessment: Refractory materials are required to operate reliably over long periods under high-temperature conditions; therefore, a thorough understanding and enhancement of their high-temperature performance are of paramount importance. Visualized high-temperature deformation technology enables real-time monitoring of the deformation behavior of refractories at elevated temperatures, facilitating the evaluation of critical performance indicators such as thermal stability and creep resistance. This approach helps optimize the formulation and manufacturing processes of refractories, thereby extending their service life and improving their performance stability.

V. Research and Applications in the Field of Metallic Materials

1. Characterization of characteristic temperature points in the metal melting process: Under high-temperature conditions, metallic materials undergo softening, melting, hemispherical deformation, and flow. Visualized high-temperature deformation techniques enable in-situ observation of the temperatures at which these transformations occur, thereby characterizing their respective characteristic temperature points.

2. Analysis of weldability between alloy and base material: Many welding phenomena are closely related to interfacial wetting behavior, particularly in the welding of high-temperature dissimilar materials such as alloys and ceramics, which is notoriously challenging at elevated temperatures. Under these conditions, the wettability between solid and liquid phases plays a crucial role in the overall welding process. Visualized high-temperature deformation analysis techniques enable efficient, real-time observation of the wettability and weldability of solder and substrate, facilitating rational design of solder compositions, optimization of welding process parameters, and enhancement of joint strength. This approach is applicable to various systems, including metal–metal, metal–ceramic, and glass–other-material joints.

VI. Technical Summary

Visualized high-temperature deformation analysis technology plays a crucial guiding role in the research, development, and production of ceramic, refractory, and metallic materials. This technology not only enables real-time observation of material deformation under high-temperature conditions, providing intuitive and accurate experimental data, but also offers robust support for formulation optimization, process improvement, and performance evaluation.
