Ni8V is a phase discovered by electrical resistivity measurements in the early 70ies . Its stability is not well known and critical evaluation of Ni-V binary system presents it as a “dashed” phase indicating that more research is necessary to completely characterize this phase . In the two available CALPHAD assessments for this system [3,4] this phase is not considered. Very recently High Throughput (HT) calculations using First Principles (FP), discuss its stability together with other compounds with the same stoichiometry .
In this work we do FP calculations with the objective to carefully investigate the ground state of this tetragonal phase. As a further objective we would like to associate this phase with Ni(V) FCC solid solution and understand the order-disorder transformation indicated by the earlier investigation of .
