In this study, the diffusion kinetics of bcc Ti-V-Mo alloys were comprehensively explored through experimental and simulation approaches. The simulated results showed good agreement with the experimental values.
In pursuit of a comprehensive exploration into the diffusion kinetics of bcc Ti-V-Mo alloys, sixteen sets of diffusion couples were prepared within the bcc phase of Ti-V-Mo alloys. These diffusion couples were subjected to annealing at 1373 K and 1473 K. Composition profiles were obtained by means of the electron probe microanalysis technique (EPMA). The calculation of diffusivities in bcc Ti-V-Mo alloys was performed using the Whittle-Green and Hall methods. Based on available thermodynamic descriptions, the atomic mobility parameters of the bcc Ti-V-Mo system were assessed by using the DICTRA module of the Thermo-Calc software. A comparison is made between the simulated composition-distance curve and the diffusion path with the experimental values, revealing a significant level of concordance.
