WebMay 1, 1991 · Abstract Grain-boundary diffusion (GBD) measurements made in α-Zr have been compared with interphase-boundary diffusion (IBD) made in the two-phase field α + βZr of Zr-2·5% Nb, with the aim of gaining a better understanding of the behaviour of these boundaries in Zr-based materials, which are relevant for the nuclear industry. In addition …WebIt is found that both Mo and Pd introduce a beneficial volume effect. Studies of the electronic structures show that its strong bonding capability makes Mo a cohesion enhancer (-0.90eV) for the Fe Σ3 (111) grain-boundary. By comparison, its weak bonding capability leads Pd to be a weak embrittler (+ 0.08 eV).
