Abstract The surface segregation of P and the embrittlement, also their rela-tions, of Ni-P amorphous annealed at temperatures below crystallization have beeninvestigated. A P-depleted layer was found nearby the surface during annealing.The P-depleted layer became thicken and the depletion of P became severe as theincrease of annealing temperature. The mechanism of elementary redistrib utionand annealing embrittlement during relaxation Was discussed on the viewpoint ofthe activation energy of atomic diffusion in Ni-P amorphous being variables.

Key words: Ni-P amorphous element redistribution annealing embrittlement
