논문 초록 (Abstract)
The effects of cold rolling on the mechanical properties of monolithic Vitreloy 1 (Zr41.2Ti13.8Cu12.5Ni10Be22.5) BMG and ductile phase reinforced in-situ composite (Zr56.3Ti13.8Cu6.9Ni5.6Nb5.0Be12.5) have been investigated. The bend strength of the as-cast composite was lower than that of the as-cast monolithic BMG. However, the bend deflection of the as-cast composite (∼1.0 mm) was significantly higher than that of the as-cast monolithic BMG. The ductility of the monolithic BMGs is improved by cold rolling. In contrast, the ductility of the metallic glass matrix composite is deteriorated after cold rolling. Thi
