상세내용 Abstract
For thermal neutron shielding applications, high boron amorphous ribbons with the compositions of Fe72-xB25-
Mo3Crx (where x = 0, 5, 10, 15 or 20 at%) have been developed. From the morphological and compositional
analysis of vein patterns formed on the fracture surfaces of the ribbons, the segregation of boron within shear
band regions was identified and discussed with reference to “free volume concentration” and “temperature rise”
models that had been proposed independently. High boron amorphous ribbons with optimum amounts of Cr
exhibit excellent thermal neutron shielding efficiency in combination with mechanical properties such as tensile
strength and bending flexibility. Moreover, corrosion resistance of the amorphous ribbons can be effectively
enhanced through proper Cr additions, thereby expanding their structural applications in the nuclear industry.
