Local melting

Exceeding the solidus temperature and melting of metallic materials. Particularly at too high operating temperatures or too high temperatures duringheat treatment, local melting points may occur in the structure. This occurs mostly in low-melting phases and eutectics and in the structural range around the grain boundaries. The grain boundaries are potential subject to segregation during solidification and often have a lower solidus temperature than the matrix material or the structural matrix.
