Cold rolling and mechanical properties of unidirectionally solidified Al–Al3Ni strip produced by an open type, horizontal, heated mold continuous casting process were investigated. As-cast and heat-treated strips were used as starting materials for cold rolling. Cold rolling was done in two ways in which the rolling direction is parallel and perpendicular to the casting direction, i.e., the longitudinal direction of Al3Ni fiber. Edge cracking during cold rolling was reduced by the heat treatment, and also by cold rolling perpendicular to the fibers. Corresponding to edge cracking, lateral spread of the strip was greater in the case of cold rolling parallel to the fibers than in that perpendicular to the fibers. Heat treatments before cold rolling reduced the tensile strength of rolled sheets, while cold rolling enhanced the strength of cast strips. Although tensile strength of the as-cast strip largely depended on the direction of the fiber alignment, cold rolled strips showed less anisotropic tensile properties.
