When does a liquid system start to solidify?
The solidus is the locus of temperatures (a curve on a phase diagram) below which a given substance is completely solid (crystallized). The solidus temperature specifies the temperature below which a material is completely solid, and the minimum temperature at which a melt can co-exist with crystals in thermodynamic equilibrium.
Solidus Temperature. The solidus temperature is the temperature at which a particle with a certain composition starts to form a solid phase-liquid phase system. From: Progress in Energy and Combustion Science, 2012
Mar 26, 2014 · Simply put, liquidus is the lowest temperature at which an alloy is completely liquid; solidus is the highest temperature at which an alloy is completely solid. Pure metals are fluid, and they melt at a single temperature.
The liquid system begins to solidify when the temperature cools to the liquidus temperature. The solidus is represented by a line on a phase diagram that separates a solid phase from a solid + liquid phase region. The system is not completely solid until it cools below the solidus temperature.
Nov 26, 2020 · The liquidus temperature is the temperature above which the system is entirely liquid, and the solidus is the temperature below which the system is completely solid. Between these two points the liquid and solid phases are in equilibrium.
The solidus is the highest temperature at which an alloy is solid – where melting begins. The liquidus is the temperature at which an alloy is completely melted. At temperatures between the solidus and liquidus the alloy is part solid, part liquid.
At low temperatures, the material of any composition is solid; at higher temperatures there is a two-phase liquid-plus-solid region, a liquid region, a liquid-plus-vapor region and, at very high temperatures, an all-vapor region.
