“…Vanadium self-diffusion in b-phase have been studied by several groups using either radioactive isotopes [51][52][53][54][55][56] or nuclear magnetic resonance. [57,58] Diffusion measurements for the binary Ti-V system were performed by Murdock et al [59] and by Murdock and McHargue.…”

Diffusion in the Ti-Al-V system is studied and a CALculation of Phase Diagrams (CALPHAD) diffusion mobility description is developed. Diffusion couple experiments are performed to obtain diffusion paths in the hcp phase at 923 K, 1023 K and 1123 K. The diffusion coefficient of V in the hcp-Ti phase is found to decrease with increasing Al alloying. A forward-simulation analysis is used to evaluate the impurity diffusion coefficient for Al and V diffusion in the hcp Ti-V and the Ti-Al systems which are used as input in the mobility modeling. The composition dependency for the diffusion in the hcp phase in the ternary system is accounted for and a CALPHAD diffusion mobility description is obtained by directly optimizing the mobility parameters as a function of the experimental composition profiles from the diffusion couples. Both experimental data and previous diffusion mobility descriptions in the literature for the bcc Ti-Al-V phase are adopted. A complete description of diffusion in both the hcp and bcc phases for the Ti-Al-V system is presented with the aim to be used for design of Ti alloys and processes.

“…Thus the variation in the diffusivity D with temperature has the same character as the self-diffusion in V (Lundy and , Peart 1965, Agarwala, Mwarha and Anand 1968, Pelleg 1974, Macht, Frohberg and Wever 1979, Ablitzer, Haeussler and Sathyaraj 1983. Diffusion of other solutes of the elements in the first long period for which data were reported seem to define a linear Arrhenius relationship over an extended temperature range (Pelleg 1975(Pelleg , 1986.…”

“…[14][15][16][17][18][19] In all these works, the 48 V isotope has been studied, except in the work by Günther et al [18] where the 51 V isotope was studied. Single crystals [14][15][16][17]19] as well as polycrystals [14,17,18] were investigated. Putting all these studies together, the vanadium Section I: Basic and Applied Research self-diffusion coefficient has been measured from the temperature 724 to 1642°C.…”

Assessments of diffusion mobility parameters are performed for the bcc Cr-V-Fe alloy system by taking available literature data into account. The main focus is on the diffusion of V in the bcc phase where, in addition to all binaries, ternary interaction parameters are assessed. An experiment is performed in order to study the coarsening of V-rich MC carbide, where the diffusion of V is believed to be of major importance. The measured coarsening rate is compared with the rate calculated using DICTRA, and found to be in satisfactory agreement. The aspects of coarsening experiments as a method to evaluate diffusion mobility data are discussed.
