Vickers microhardness, nanohardness, tension tests, notch and fatigue precrack toughness tests, and controlled monotonic and cyclic strain experiments via bending over mandrels of different diameter have been performed on two different chemistries of Fe-based (Fe-Si-B) metallic glass ribbons. The tensile strengths of Fe73.5Cu1Nb3Si13.5B9 were 2000 +/- A 100 MPa and 1640 +/- A 35 MPa for Fe78Si9B13, which is consistent with the microhardness trends. High notch toughness (e.g., 89 +/- A 0.9 MPam(1/2) - Fe73.5Cu1Nb3Si13.5B9; 94.5 +/- A 5.5 MPam(1/2) - Fe78Si9B13) and fatigue precracked toughness of 76 MPam(1/2) for the Fe73.5Cu1Nb3Si13.5B9 and 80 MPam(1/2) for the Fe78Si9B13 were obtained. Flex-bending cyclic fatigue tests revealed a fatigue limit of 385 MPa for Fe78Si9B13 ribbons, whereas the more brittle behavior of the Fe73.5Cu1Nb3Si13.5B9 ribbons prevented the generation of flex-bending fatigue data. These results are discussed in the light of recent work on metallic glass systems.
