采用时间分辨x射线衍射技术对不锈钢焊缝的凝固过程进行了分析。利用波动束和新型x射线探测器，在倒易晶格空间中分析了凝固过程中的相演化以及凝固过程中的晶粒结构和液相还原。此外，为了估计激发杂散颗粒形成的温度，使用带浸入式光纤的辐射温度计测量了焊缝中心线的温度分布。
The solidification process in stainless steel welds was analyzed using a time-resolved X-ray diffraction technique. By using an undulator beam and a novel X-ray detector, not only the phase evolution during the solidification process but also the grain structure and liquid reduction during the solidification process were analyzed in the reciprocal lattice space. Furthermore, to estimate the temperature that stimulates stray grain formation, the temperature profile at the centerline of a weld bead was measured by using a radiation thermometer with immersion-type optical fiber.
