Resumen:
51Cr diffusion along grain boundaries in polycrystalline a-Zr was measured by means of the radiotracertechnique in the temperature range 449–680 K. The use of Harrison´ s C and B kinetics provided direct dataabout grain boundary diffusivity (Dgb) and the apparent grain boundary diffusivity (Pgb) in the temperaturerange of power reactors service. The grain boundaries segregation factor s of Cr in a-Zr was determinedat the limit of very dilute solute concentration.
