상세내용 Abstract
Fe based amorphous alloys with high boron and gadolinium contents have been developed through a systematic
alloy design technique for neutron shielding applications. Amorphous ribbons with the Gd content
up to 10 at.% were prepared by a melt-spinning method and used as reinforcements within polyester
matrix and concrete matrix, respectively. Excellent neutron shielding efficiency about 75% was obtained
from the polyester hexahedron composites (5 cm  5 cm 1 cm) including only 1 vol% ribbon with the
composition of Fe72B15Mo3Gd10. Moreover, a concrete composite (u 10 cm  5 cm thick) in which the
amorphous ribbons with the composition of Fe72B24.5Mo3Gd0.5 were uniformly distributed exhibited neutron
shielding efficiency of around 86% demonstrating the applicability of amorphous ribbons as reinforcements
in various composites for neutron shielding facility constructions.
