利用强流同步辐射探针对Fe-Cr-Ni合金焊接过程中的定向凝固模式进行了表征。从而详细揭示了快速凝固过程中的晶体生长过程，并对峰值形态进行了系统的分析，为控制焊缝组织提供了必要的信息。讨论了初生相和第二相的晶化时间。此外，晶格旋转相称（i）每个枝晶和（ii）在枝晶中的微晶的可能性被建议。
Characterizing of directional solidification mode of Fe-Cr-Ni alloys during welding was performed using intense synchrotron radiation probe. Consequently, the crystal growth in the rapid solidification process was revealed in detail and the peak profile was systematically analyzed in order to acquire the essential information for controlling the weld microstructure. Then, the crystallization timing of the primary and secondary phases was discussed. Furthermore, the possibility of the lattice rotation to commensurate (i) each dendrite and (ii) crystallites in the dendrites is suggested.
