Abstract
Possibility of making laminate, which is made directly from molten metal and the rapidly solidified aluminum alloy foils were laminated, was investigated. To laminate foils into multi-layer laminate from molten metal, rotating disk process was devised. Sticking of the first foil and laminate to the surface of the disk is most important to make the laminate. Fundamental factors which affect sticking length of the foil are disk temperature, disk speed, disk material, number of slit. Disk was heated up to 100°C. Disk was made from SUS304 and rotating speed was up to 47m/s. Nozzle which has 1-7 slits was used to eject molten metal. Al-12mass%Si alloy was melted in air and ejected onto the disk. Laminate consisting of more than 50 layers of foils can be cast by rotating disk method. Cooling rate of laminate in the range of 103-104°C/s is attained. There is not much difference in cooling rate of each layer. Tensile strength of laminate is about 300Pa. Each layer of the laminate is not torn along interface by bending.
