What is solidus and liquidus temperature?

What is solidus and liquidus temperature?

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.

What is a solvus temperature?

Definition of solvus : a curve on a temperature-composition diagram indicating the limits of solubility of one solid phase in another — compare liquidus, solid solution, solidus.

What do you mean by eutectic temperature?

Eutectoid: Eutectoid refers to a homogeneous solid mixture that forms from cooling two or more melted metals to a certain temperature. Eutectic Temperature or Eutectic Point: The eutectic temperature is the lowest possible melting temperature for all of the mixing ratios of the component substances in a eutectoid.

What is liquidus and solidus lines?

In particular, the solidus line defines the temperature below which the phases in the diagram are solid, while the liquidus line defines the temperature above which the phases are completely liquid.

What is liquidus solidus and solvus line?

Therefore, the liquidus, solidus, and solvus temperatures are those in which their respective lines intersect the vertical dashed line at the composition of interest. The eutectic temperature is the same, regardless of the composition.

How do you find the temperature of a liquidus?

Liquidus temperature of a steel is calculated from its chemical composition according to the so far proposed procedures by simply summing up the iron melting point lowering effects of all in the steel contained elements Xi, as they are given by approximating the iron liquidus curves with the straight lines in the …

Why is eutectic temperature low?

Simply put, eutectic temperature is the lowest temperature a solution can possibly achieve. Solute molecules interfere with the solvent’s ability to freeze, and they lower its freezing point. This is why salt water freezes at a lower temperature than freshwater.
