采用同步辐射X射线显微断层摄影技术观察到一种普通的、可使用的钢。空间分辨率已被优化，使用不同的实验条件下的测试对象。合理的高分辨率，这是接近的投影型X射线断层摄影的理论上限，已经实现了一个合理的大标本。它的应用使得可以清楚地观察钢中的疲劳裂纹及其张开行为，并演示一些定量的力学评估。
A common, serviceable form of steel has been observed by employing synchrotron X-ray microtomography technique. Spatial resolution has been optimized using a test object with varying experimental conditions. Reasonably high resolution, which is close to the theoretical upper limit for the projection-type X-ray tomography, has been achieved for a reasonably large specimen. Its application has made it possible to clearly observe a fatigue crack and its opening behavior in steel, and to demonstrate some quantitative mechanical evaluations.
