Abstract
Interdiffusion studies have been carried out in the bcc phase of the ZrTi alloy system using diffusion couples of zirconium and ZrTi alloys Geoscan electron microprobe was employed to establish the concentrationpenetration profiles in the diffusion zones and the interdiffusion coefficients were evaluated by BoltzmannMatano analysis The concentration and temperature dependence of the diffusivity have also been examined Present studies further showed that the diffusivity in the ZrTi system in theβphase could be expressed by an equation similar to that given by Vignes and Birchenall for vacancycontrolled interdiffusion in fee solid solutions
