Crystal growth of metals during solidification (polygonal & dendritic)

In polygonal crystal growth, the solidification heat is dissipated through the crystal, and in dendritic crystal growth, it is dissipated through the melt. In this video we go into more detail about the different types of crystal growth during the solidification of metals. 00:00 Solidification of metals (supercooling & nucleation) 00:59 Crystal growth 01:52 Polygonal crystal growth 02:50 Three-zone microstructure of a casting 03:45 Dendritic crystal growth 05:00 Snowflake
