Directional Solidification and Growth of Faceted Phases
The faceted phases exist widely in alloys solidification,whereas the present study including solidification theory and experimental research mainly focus on the investigation of non-faceted phases.As a result,many solidification phenomena caused by the growth of faceted phases remain unclear.With the development of the novel materials,such as intermetallic compound,thermoelectric material,and biomaterial,faceted phases formed in these materials will receive more attention.This paper reviews the directional solidification and growth of faceted phases involving the solidification condition and growth mechanism of the faceted phases.The theoretical analysis method is also addressed.Additionally,we briefly put forward some important unsolved problems that deserve to further explore in solidification of faceted phases.
