Viscosity: Al-Cu and Cu-Al-Si

The viscosity thermophysical property data is included with the TCS Al-based Alloy Database (TCAL) as of version 7 (TCAL7).

Al-Cu

Al-Cu and Al-Si are assessed based on experimental data. For Al-Cu, the data from Schick [2012Sch] is used for fitting the parameters but data from Konstantinova [2009Kon] is also shown.

Cu-Al-Si

The following plot shows the calculated viscosity of Cu-Al-Si alloys as a function of composition at 1375 K.
