Using our continuous casting apparatus, Al-Cu (4%) slabs were made under various coditions, and we investigated the segregation that appeared in the slabs obtained. The results are as follows: The degree of segregation is very low when the conditions of casting—casting velocity, casting temperature, descending velocity and cooling velocity—are suitable. The structure of the slabs is shown in photo. 3; in the photographs we see fine granular structure only as was expected from our diagram (Fig. 1).
