When heated, most alloys change gradually from being totally solid to being totally liquid over an extended temperature range. The liquidus is the temperature at which the alloy is totally liquid. Note that in the case of eutectic materials, there is no such pasty range See solidus and pasty range.
Temperature at which an alloy becomes fully liquid. See also ‘solidus'
On a graph of temperature vs composition, a diagram showing the maximum solubility of a solid component or phase in the liquid phase.
The line on the iron carbon phase diagram where above it the material is liquid.
The lowest temperature at which a material is completely liquid.
The temperature at which solidification of metal begins on cooling and the temperature at which the last portion of solid metal becomes liquid on heating.
In a constitutional diagram, the locus of points representing the temperatures at which various components commence freezing on cooling or finish melting on heating.
In chemistry, materials science, and physics, the liquidus is a line on a phase diagram above which a given substance is stable in the liquid phase. Most commonly, this line represents a transition temperature. The liquidus may be a straight line, or it may be curved, depending upon the substance.
