Auger electron spectroscopy of in situ fractured samples was used to determine the grain boundary concentrations of phosphorous and silicon in polycrystalline Fe-Si-P alloys annealed at 800^oC for 100 h. These measurements were supplemented by mechanical testing and evaluation of fracture surfaces to obtain values of the energy of intergranular fracture. The effect of segregated phosphorus on the energy of intergranular fracture is discussed

Spektroskopie Augerových elektronů byla použita na stanovení koncentrace fosforu na hranicích zrn polykrystalických slitin Fe-Si-P žíhaných 100 hodin při 800 ^oC. Měření byla doplněna lomovými testy a vyhodnocením energie interkrystalického lomu
