논문 초록 (Abstract)
The mechanical properties of Vitreloy 1 (Zr41.2Ti 13.8Cu12.5Ni10Be22.5) and in-situ composite (Zr56.3Ti13.8Cu6.9Ni 5.6Nb5.0Be12.5) upon shear band formation by conventional cold rolling have been monitored together with microstructural evolutions. Following the formation of primary shear bands with 45 degrees to the rolling direction, secondary shear bands were developed to the rolling direction. The order of the shear bands formation appeared vise versa for the composite system. The ductility of cold-rolled monolithic Vitreloy 1 showed a large enhancement, but those of the cold-rolled composite were lowered. It appears that work hardening of the incorporated ductile phase is responsible for deteriorating mechanical properties of the composite.
