Density and Molar Volume
The TCS Cu-based Alloys Database (TCCU) contains a database of molar volume and thermal expansion coefficients of all phases. By applying the TCCU database, the molar volume and the density can be well predicated. In this example, the density of various Cu-Co-Fe melts varying with temperatures was calculated with TCCU and Thermo-Calc.
