Zr diffusion in alpha-Ti measured by RBS and HIRBS
This study deals with the diffusion of Zr in alpha-Ti using ion beam techniques to measure shallow penetration profiles non-destructively. Conventional Rutherford backscattering with He ions (RBS) was used in the temperature range 823-1012 K, and heavy ion Rutherford backscattering (HIRBS) in the range 873-1133 K. Arrhenius plots are presented for all the data calculated. In the temperature range in which both techniques were used, the agreement of the plots was fairly good. Outside this range a straight line was obtained for alpha-Ti whereas the results for alpha-Zr yielded a pronounced curve. The latter observation was believed to be due to an enhancement of self-diffusion by fast-diffusing impurities such as Fe forming rapidly diffusing impurity-vacancy pairs.
