Abstract
In this paper, the influence of the production conditions on the quality and mechanical behaviour of metallic glass ribbons will be presented, taking two amorphous alloys, Ni₈₁P₁₉ and Fe₆₄Co₂₁¹¹B₁₅ as examples. These alloys have been chosen for the numerous results reported, for similar compositions, in the literature as well as for the possibility to easily carry out neutron scattering experiments. All results, from neutron diffraction at small and large angles as well as tensile tests within the Weibull statistics and scanning electron microscopy of the fracture surfaces, show that the best quality and mechanical properties are achieved after quench from an overheated melt.
