Pandat Example Results


In CAMM, Pandat® 5.0 has been used for preliminary calculations on titanium alloys. For this the PanTitanium database has been used. Some of the work is aimed at finding:

  1. Equilibrium volume fraction of different phases in alloys having different compositions
  2. Variation of volume fraction of different phases with change in temperature
  3. Plotting b approach curves for b titanium alloys
  4. Determining the miscibility gap of b titanium alloys

                                     
Some of the calculated plots are shown below:

A simple binary Ti-V phase diagram showing the a (HCP_A3) and b (BCC_A2) phases. Also shown is the metastable b miscibility gap (BCC_A2 + BCC_A2)

Ti-5Al-5Mo-xV-3Cr Isopleth with varying V wt%.
The stable phases shown are a (HCP_A3), b (BCC_A2) and a2(DO19 Ti3Al).
The metastable b miscibility gap is superimposed on the plot (BCC_A2 + BCC_A2).
Also marked in dotted lines is the commercial Ti5553 alloy composition.

A simple binary Ti-Al phase diagram showing the liquid, a (HCP_A3) and
b (BCC_A2) phases.

Ti-xNb-7Zr-5Ta isopleth with varying Nb wt%.
The stable phases shown are a (HCP_A3) and b (BCC_A2).
The metastable b miscibility gap is superimposed on the plot (BCC_A2 + BCC_A2). Also marked in dotted lines is the commercial Tiosteum alloy composition.
