A given work presents the experimental evidence on fracture stress of amorphous tapes made on the base of an iron. Investigation of the tapes with different content of such alloying elements as Co and Mo enables to conclude about their influence on amorphous alloy strength. Approximation of experimental data on fracture stress of amorphous tapes by means of the three-parameter Weibull distribution allows estimating threshold fracture stresses of studied alloys. As also ascertained, the curves of distribution density for fracture stresses of analysed tapes are symmetric for all alloys. This is their difference from strength distribution for typical brittle materials (ceramics, glasses, etc.) described by distribution curves, which are essentially asymmetric within the range of low fracture stresses.
