X射线三维成像“飞入寻常实验室”

Core Viewpoint - The research team from the University of Michigan has developed a laboratory-grade 3DXRD system that successfully implements X-ray three-dimensional diffraction technology (3DXRD) in conventional experimental environments, making this advanced technique accessible for materials science research [1][2]. Group 1: Technology Development - The new laboratory-grade 3DXRD system utilizes a liquid metal jet anode, which avoids melting risks and significantly enhances X-ray output strength compared to traditional solid metal anodes [2]. - The system allows for the construction of three-dimensional images of materials by exposing millimeter-sized samples to extremely high-intensity X-ray beams, which are a million times stronger than medical X-rays [1][2]. Group 2: Research Implications - The laboratory-grade 3DXRD system accurately identified 96% of crystal structures in titanium alloy samples, demonstrating superior performance, especially for large crystals over 60 micrometers [2]. - This breakthrough enables researchers to conduct preliminary experiments at any time, overcoming the limitations of waiting for access to synchrotron facilities, which typically have a maximum experimental time of six days [2]. Group 3: Future Prospects - The research team anticipates that equipping the system with higher sensitivity detectors will allow for the capture of finer crystal features, further enhancing the capabilities of materials research [2]. - The development of this technology is expected to revolutionize the study of materials under repeated stress, such as thousands of cyclic load tests, providing deeper insights into the long-term evolution of material properties [2].
