Using a process called Fused Spinning Deposition (FSD) Al-Cu alloy melt flowing out through a small nozzle located at the bottom of the quartz tube container was rapidly solidified in a tube form on a rotating copper substrate. The fusion weldability between layers, shape stability and microstructures of the tube specimens were investigated as a function of alloy composition, superheat and rotation speed of the substrate. Good weldability between the layers and steady shape forming were achieved with smaller superheat and higher rotation speed. Better shape stability was obtained for hypo-eutectic alloys. The microstructure of the tube specimens subjected to the fused spinning deposition process was found to consist of fine equiaxed grains and the specimen exhibited tensile strength 1.5 times higher than metal-mould cast alloys with a fine columnar structure. The solidification analysis showed that the equiaxed grain structure is formed as a result of the cyclic remelting and solidification process.
