Diffusion of titanium and niobium in b. c. c. Ti--Nb alloys
- Univ. of Illinois, Urbana-Champaign, IL (United States)
The diffusion coefficients for titanium and niobium radioactive tracers were simultaneously measured in Ti, Ti/sub 94.6Nb5.4, Ti80.4Nb19.6, and Ti64.3Nb35.7 over the temperature range from 950°C to 1511°C using standard lathe sectioning techniques. The samples were initially heat treated by annealing above the α-ß phase transition temperature and then either cooling slowly to room temperature or quenching. The room temperature crystal morphology was then examined using x-ray diffraction. Alloy concentrations were chosen both to suppress the α-ß transition and to obtain the metastable ω-phase.
