Abstract：
Solidification is an essential process in versatile technologies. Thus, it is vital to understand solidification
behaviour at multiple scales to realize effective design and precise control of the solidification process. After decades of
investigation, in situ studies of solidification have revealed the evolution of solidification microstructures at the microscale,
which has gradually advanced to the nanoscale. In this paper, the main results of in situ investigations of solidification
behaviour at the microscale and nanoscale are reviewed, the in situ investigation methods for solidification are summarized,
the transition behaviours of cellular and dendrites as well as their evolutions and influences are revealed, and in situ
analysis of the solidification and microstructure characteristics of equiaxed grains and eutectic systems is presented. This
review also intro
