Phase Diagrams and Solidification in Alloys

The plateau indicates that the temperature remains constant while the metal solidifies, revealing the energy release known as latent heat of fusion.

The phases present are a mixture of liquid copper and a nickel-rich solid.

In an alloy, the liquidus and solidus points are separate, indicating a range of temperatures for solidification as opposed to a singular melting point in pure metals.

The temperature at which a liquid metal starts to solidify. It's the starting point of the solidification process on the cooling curve for an alloy.

The temperature at which a metal completely solidifies. It's the end point of the solidification process on the cooling curve for an alloy.

A type of phase diagram that illustrates the melting temperatures of different compositions of a system, showing regions of liquid, solid, or a mixture of both.

The extended temperature range observed during the solidification of an alloy, as opposed to the single point solidification of a pure metal.

A solid solution where the components of a material are not completely soluble, leading to the formation of separate solid solutions.
