solidification
Solidification is a cooling process in which molten metal is converted into a solid by lowering the temperature. It is an aspect of utmost importance in metal component manufacturing in shaping the characteristics of metals. The process is inherent in casting and metal production.
Key Features:
- Phase Change: The metal changes from liquid to solid by cooling below its melting point.
- Grain Structure Formation: The rate of cooling determines the size and shape of the metal grains, which, in return, alters its strength.
- Defect Prevention: Controlled cooling can prevent defects such as shrinkage and/or porosity.
The objective of solidification is the manufacture of metal components that have specific shapes and properties. It is a common practice observed in the industries of casting, welding, and additive manufacturing. With steady improvements in solidification techniques, product quality has increased even further and defects have been reduced, enhancing performance.
