Additive manufacturing (AM) can realize the rapid solidification for the formation of ultra-fine solidification microstructures and/or crystal growth reaching the marginal stability condition. The TEM observation of the nucleation and growth behavior of BCC dendrite embedded in Fe-based metallic glasses offers an unique opportunity for clarifying the morphology of the ultra-fine dendrite for the development of AM. The present study reported the network tele-microscopy observation of BCC-Fe dendrites embedded in an Fe-Si-B amorphous matrix obtained by the in-situ heating of TEM specimens using the ultra-high voltage electron microscope Hitachi H-3000.
