研究了开式水平热型连铸定向凝固Al-Al3Ni带材的冷轧及力学性能。铸态和热处理带材被用作冷轧的起始材料。冷轧以两种方式进行，其中轧制方向平行于和垂直于铸造方向，即，Al3Ni纤维的纵向。冷轧过程中的边缘开裂减少了热处理，也通过冷轧垂直于纤维。与边裂相对应，平行于纤维方向冷轧时带材的横向扩展大于垂直于纤维方向冷轧时带材的横向扩展。冷轧前的热处理降低了轧制板的抗拉强度，而冷轧提高了铸带的强度。虽然铸态带材的拉伸强度在很大程度上取决于纤维排列的方向，但冷轧带材的各向异性拉伸性能较低。
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.
