Phase diagram for alloy system is a fundamental information in materials R&D. However, the phase diagram data for practical alloy systems are not always available.

The purpose of the present database is to distribute calculated phase diagram information for practical steel alloys, which is not available in literature. The calculation of phase diagrams is based on the CALPHAD technique.

Select alloy group first, then select alloy system to see the list of phase diagram data and relevant literature information.

It should be noted that the calculated phase diagrams can be erroneous and should not be trusted 100%.
