Structural relaxation of amorphous Fe_{40}Ni_{40}B_{20} alloy has been studied by the method of angular correlation of positron annihilation. Inexpressive changes of the spectra after the annealing for 2 x 10^{3} min at 473 K suggest some changes in topological order. The relatively low sensitivity of positron annihilation to the structural relaxation of the amorphous alloy is probably caused by the high density of vacancy-like defects in the alloy.
