The solidus temperature specifies the temperature below which a material is completely solid, [2] and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium. Liquidus and solidus are mostly used for impure substances (mixtures) such as glasses , metal alloys , ceramics , rocks , and minerals .

The metal with the highest melting ... Iron: 7.874: 1,811: ... The temperature at which melting begins for a mixture is known as the solidus while the temperature ...
The solidus is the temperature below which the substance is stable in the solid state. The liquidus is the temperature above which the substance is stable in a liquid state. There may be a gap between the solidus and liquidus; within the gap, the substance consists of a mixture of crystals and liquid (like a "slurry"). [2]
Forging temperature is the temperature at which a metal becomes substantially more soft, but is lower than the melting temperature, such that it can be reshaped by forging. [1] Bringing a metal to its forging temperature allows the metal's shape to be changed by applying a relatively small force, without creating cracks.
The independent variable (X-axis) is time and the dependent variable (Y-axis) is temperature. [1] Below is an example of a cooling curve used in castings . The initial point of the graph is the starting temperature of the matter, here noted as the "pouring temperature".
Boca Raton, Florida, 2003; Section 6, Fluid Properties; Critical Constants. Also agrees with Celsius values from Section 4: Properties of the Elements and Inorganic Compounds, Melting, Boiling, Triple, and Critical Point Temperatures of the Elements Estimated accuracy for Tc and Pc is indicated by the number of digits.
The temperature of total solidification is the solidus of the alloy, the temperature at which all components are molten is the liquidus. The mushy state is desired where a degree of plasticity is beneficial for creating the joint, allowing filling larger gaps or being wiped over the joint (e.g. when soldering pipes).
