Abstract

Amorphous gray iron ribbons can be used as reinforcement fibers in the manufacture of composite materials due to a unique combination of high yield strength and a high hardness with good ductility. Amorphous ribbons with a thickness of 20 μm and width of 1.5 mm of Fe73Cr8PxSi12-xC7 (x = 9, 10, 11) alloy were prepared by melt-spinning method. The elaborated alloys were structurally investigated by x-ray diffraction (XRD) and differential scanning calorimetry (DSC), while the mechanical properties were investigated by tensile microhardness and bending tests. It was found that increasing P content up to 10 atomic percentages led to a brittle material.
