In this section we employ the Bayesian framework and methods introduced in the previous sections for the development of a thermodynamic property model for the alpha, beta and liquid phases of Hafnium. In Section 3.1 we give an overview of Hafnium. In Section 3.2 we discuss how the **data** was collected and any corrections which were applied. In Section 3.3 we present our analysis methods and in Section 3.4 the model selection criteria are presented. Our main results are given in Section 3.5.
