Liquidus and Solidus

The TCS Steel and Fe-alloys Database (TCFE) can satisfactorily predict the liquidus and solidus temperatures in various commercial steels and model alloys. In addition, the accuracy to predict the correct primary phase to form from the liquid is very high.

In this example, measured liquidus temperatures are compared with the calculated ones for various steels.

Experimental liquidus temperatures for various steels compared with calculations with the TCFE database.
