Liquidus

The liquidus temperature indicates the temperature of an alloy or a glass, from below which the mixture starts to solidify from a homogeneous liquid phase. The temperature achieved in homogeneous solidification, on the other hand referred to as the solidus.

Between solidus and liquidus temperature the mixture is pulpy in alloys, there are solid and liquid phases coexist.

The temperature range between solidus and liquidus temperature is called the melting interval.

In pure metals and eutectic alloys liquidus and solidus fall together, eg ISO BSn63Pb 178 (L- Sn63PbAg ) at 178 ° C. Here the transition occurs abruptly from solid to liquid and is called the eutectic point.
