Coring

For geological coring, see core sample.

Coring happens when a heated alloy, such as a Cu-Ni system, cools in non-equilibrium conditions. This causes the exterior of the material to harden faster than the interior. Coring causes the exterior layers to retain more of the higher melting temperature element. In this case, the dendrite arms formed from the exterior have a different composition than the alloy in the inner regions, resulting in a local compositional difference.
