| Abstract: | There are many sorts of flows of melten liquid, it plays an important role in the metal's metallurgy and solidification processes. It was summarized in present paper that the liquid flow acted in the transfers process, solidification structure and componential segregation. Through controlling the mode and the action of liquid flow, the transfers action during solidification could be adjusted in order to improve the solidification structure and componential segregation. It is worth reading for man in relative fields. |
