Laves Phase

The TCS Steel and Fe-alloys Database (TCFE) contains an extensive description of the Laves phase. This description shows satisfying accuracy of the predictions compared to experimental information [2004Sah; 2010Pan]. Below compares the amount of different phases as a function of temperature two commercial steels.
