Al-Cr-Ni Thermodynamic Re-Assessment of the Ternary System
MetadataShow full item record
A re-assessment of the ternary system A1-Cr-Ni following Dupin's thesis work using a single Gibbs energy function for the gamma and gamma prime phases is presented taking into account new experimental liquidus temperatures. The disordered bcc A2 and ordered B2 phases are also modelled with a single equation. The existence of vacancies as defects in this structure is described. The other phases are modelled as substitutional solutions, or as stoichiometric or non-stroichiometric binary compounds. The present assessment is limited to the sub-system A1Ni-Cr-Ni where no ternary phase exists. The parameters describing the Gibbs energy of all the assessed phases.
