Al-In alloys with monotectic and hyper-monotectic compositions were produced by vertical Ohno Continuous Casting (OCC) technique. The resultant alloys had a diameter of 8 mm and a length of 400 mm. A very beautiful surface and a unidirectional macrostructure were obtained by controlling the mold temperature and solidification velocity regardless of the alloy compositions. Even in the hyper-monotectic composition samples the Al-In alloys exhibited a good distribution of β-In particles throughout all sections without any segregation of β-In phase. The morphology of the microstructure depended on the growth velocity and temperature gradient of the melt.
