Abstract
Iron based amorphous ribbons with the nominal compositions of $(Fe_{79}C_{11}B_8Si_2)_{100-X}Cr_X$ (X = 0,2,4,6,8 at%) have been developed as reinforcements that can be applied to the concrete materials. Mechanical properties and glass forming ability of the ribbons can be enhanced by the optimum amounts of Cr additions that can also improve corrosion properties of the ribbons. Vein patterns typical of the fractured surface morphology of amorphous alloys have been observed on the surfaces of ribbons after tensile tests. It is inferred from the EDS analysis results of vein patterns that carbon segregations occur within the narrow shear band regions.
