Abstract
The low-superheat casting (LSC)is apromising technique for preparing semisolid billet with reduced cost due to its simple process and no requirement for sophisticated devices. In the LSC process, a slightly superheated melt is poured directly into the die ; the seed of the crystals are generated at the die surface and the casting is carried out before the crystal seeds could be re-melted. By this method shallow temperature gradient remove directional heat ext
