liquación
- In the furnace, liquation occurs when the temperature is raised enough to let certain metals liquefy while others remain solid.
Examples
-
This is called constitutional liquation if, during melting, the bulk composition is in a non-liquid region of the phase diagram, but the tie-line between the liquating phases passes through a liquid region.
Academic text (2000) -
The liquid produced during constitutional liquation can spread along grain boundaries and promote liquid film migration (LFM).
Academic text (2000) -
The metastable liquid film results from the spreading of liquid that forms from the constitutional liquation of precipitates located on the grain boundaries.
Academic text (2000) -
(c) The formation of a metastable concentration gradient in the liquid at the end of AB liquation.
Academic text (2000) -
These samples were then subjected to isothermal treatments above their constitutional liquation temperature, which produced CLFM of the grain boundaries.

It is the purpose of this study to investigate LFM accompanying constitutional liquation in alloy 718 in order to gain a better understanding of the conditions under which this phenomenon occurs.

Academic text (2000) -
Radhakrishnan and Thompson were the first to report LFM occurring in situ in the weld heat-affected zone (HAZ) as a result of constitutional liquation.
Academic text (2000) -
Since LFM was observed to occur in situ in the weld HAZ of multiphase alloys due to constitutional liquation, it is important that this phenomenon be better understood.

Etymology
Liquation comes from the Latin root liqu- meaning 'liquid' or 'to melt', the same root you see in liquid and liquidate. So in metalwork, liquation is the process of partly melting a metal mix so the liquid metal can be taken away and separated.
