Abstract
The V-Zr system was investigated by experiments and thermodynamic modeling. In experiments, 10 crucial alloys were selected, and the microstructure, crystal structure and phase transformation temperatures of the alloys were obtained using scanning electron microscopy (SEM) with energy dispersive spectrometer (EDS), X-ray powder diffraction (XRD) and differential thermal analysis (DTA). A thermodynamic modeling of the V-Zr system was then performed by considering the reviewed literature data and incorporating the present experimental results. The solution phases, liquid, hcp (Zr) and bcc(V, Zr), were modeled with the substitutional solution model, and the compound V2Zr was treated as (V, Zr)2(V, Zr) by means of two-sublattice model. A set of self-consistent thermodynamic parameters of the V-Zr system was obtained.
