Abstract
This study investigates the microstructural and compositional evolution of a ternary NbVZr alloy under varying Zr concentrations, utilizing scanning electron microscopy (SEM) imaging and energy-dispersive X-ray spectroscopy (EDS) analysis. Results show consistent overall composition across different Zr concentrations, with observable Zr-enriched regions decreasing in frequency with increasing Zr content, potentially due to destabilization effects. Microstructural analysis reveals an increase in the area fraction occupied by dendrites as Zr content increases, prompting a decrease in the interdendritic phase. A comparison with an active concurrent work on the deposition of Nb to the ternary alloy highlights similarities and differences in phase distribution and composition between the two conditions. Ternary diagrams analyses indicate that while the phases in the Zr-deposit are stable, they do not meet the criteria for the formation of a single-phase BCC solid solution.
