デンドライト 核生成・成長の電子顕微鏡その場観察†Figure 1
Typical example of in-situ TEM observation of the dendrite growth [1]
Solidification is a phase transition which is familiar to everyone and significantly important for materials science and engineering due to the casting methods. The visualization technique of the solidification process of metals stimulates the strong industrial and academic motivation for a better understanding of and control over the fundamental aspects of solidification. A new approach for clarify the solidification process focusing on the dendrite nucleation and growth, namely, in-situ TEM observation of the dendrite nucleation and growth using an amorphous alloys is performed. Figure 1 shows the typical example of the in-situ TEM observation of the bcc-Fe dendrite growth using Fe-Si-B amorphous alloys [1].
