| Abstract: | A method of producing gradient material by continuous casting using double stream pouring technique was proposed. An experimental study of AlCu/Al gradient material was carried out on self made semi continuous apparatus. The microstructure and property of the alloy was analyzed. The results show that the continuous gradient distribution in composition across the cross section of the ingot can be realized in Al Cu alloy system using the proposed method, and the microstructure, Rockwell hardness and the composition of the alloy are in good accordance with each other. |
