Heat treatments for shaping
Heat treatment of copper and copper alloys

Compositional heterogeneities in an as-cast alloy, referred to as microscopic or macroscopic segregations, are the result of high solidification rates: equilibrium within the two phases, liquid and solid, therefore has no time to establish itself.

The longer the solidification interval, the more the solute content varies from the center to the periphery of a dendrite or grain (a phenomenon known as coring)....
