Coring happens when a heated alloy, such as a Cu-Ni system, cools in non-equilibrium conditions. The center of each grain, which is the first part to freeze, is rich in the high-melting element, whereas the concentration of the low-melting element increases with position from this region to the grain boundary. This is termed a 'cored structure', which gives rise to less than the optimal properties. The distribution of the two elements within the grains is nonuniform, a phenomenon termed 'segregation'; that is, concentration gradients are established across the grains.
