Abstract
Iron based amorphous ribbons with the nominal compositions of (Fe 79 C 11 B 8 Si 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 typ-ical 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.
铁基非晶带的标称成分为(Fe 79 C 11 B 8 Si 2) 100-X Cr X (X = 0,2,4,6,8 at%),已被开发为可应用于混凝土材料的增强材料。添加适量的铬可以提高带的机械性能和玻璃化成形能力,同时还可以改善带的腐蚀性能。在拉伸试验后,在带状表面观察到典型的非晶合金断裂表面形貌的脉状图案。从脉型的EDS分析结果可以推断,碳偏析发生在窄剪切带区域内。
