Abstract

Iron based amorphous ribbons with the nominal compositions of (Fe79C11B8Si2)100-XCrX (X = XCrX (X = 0,2,4,6,8 at%) have been developed as reinforcements that can be applied to the co to the concrete materials. Mechanical properties and glass forming ability of the ribbons c ribbons can be enhanced by the optimum amounts of Cr additions that can also improve c improve corrosion properties of the ribbons. Vein patterns typical of the fractured surface m surface morphology of amorphous alloys have been observed on the surfaces of ribbons a ribbons after tensile tests. It is inferred from the EDS analysis results of vein patterns that carb that carbon segregations occur within the narrow shear band regions.
