  • Publication number: 20040050523
    Abstract: A process for transforming a metal alloy (28) having a liquidus temperature and a solidus temperature into a part solid/part liquid shaped body. The metal alloy (28) is poured in the molten state at a temperature (TMo) into a mould (10) having an essentially cylindrical mould wall (12), whereby the mould (10) at the start of filling exhibits a starting temperature that lies below the liquidus temperature, the mould (10) is set into an eccentric rotational movement at a starting temperature for the metal alloy (28) lying above the liquidus temperature and the rotational movement maintained until the metal alloy (28) has cooled to a to a discharging temperature lying between the liquidus temperature and the solidus temperature corresponding to a desired solid/liquid ratio in the shaped body and the shaped body removed from the mould (10) at the discharging temperature.
