Abstract

The effects of cold rolling on the mechanical properties of monolithic Vitreloy 1 (Zr_41.2Ti_13.8Cu_12.5Ni ₁₀Be_22.5) BMG and ductile phase reinforced in-situ composite (Zr_56.3Ti_13.8Cu_6.9Ni _5.6Nb_5.0Be_12.5) 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.
