Solidification of metals

The solidification of a melt starts from nuclei, resulting in the typical polycrystal microstructure. https://youtu.be/7xPfW2hYt8w Polycrystal A metallic material generally does not have a uniform lattice orientation (see crystallographic defects). Exceptions to this are...

Solidification can be triggered either by nuclei consisting of the same substance as the melt or by nuclei consisting of a different substance. https://youtu.be/7xPfW2hYt8w Introduction As explained in the article on solidification conditions, the...

During solidification, heat is released, which is called heat of crystallization or heat of solidification. It counteracts the external cooling. https://youtu.be/7xPfW2hYt8w Introduction The hand warmer described in the article solidification conditions shows another phenomenon...

Two conditions must be met for solidification: The melt must be supercooled and nuclei must be present in the melt. https://youtu.be/7xPfW2hYt8w Introduction The origin for the formation of a microstructure is usually the...
