The grain boundary segregation of Bi in Ni polycrystals doped with Bi and annealed at 400-1000degreesC was investigated by Auger electron spectroscopy (AES). In the Ni-50 wt. ppm Bi alloy the amount of Bi segregation at grain boundaries decreases continuously with increasing temperature. Abrupt changes of segregation were observed in Ni-90 wt. ppm Bi and Ni-160 wt. ppm Bi alloys between 400-500 and 900-1000degreesC, respectively. (C) 2004 Acta Materialia Inc.
