摘要： PROBLEM TO BE SOLVED: To provide a forming method, by which a semi-solidified metal finely and uniformly crystallized with the primary crystal Si in the hyper-eutectic Al-Si base alloy, is produced at low cost in a short time and thereafter, press-formation is applied to this metal.
SOLUTION: When the semi-solidified metal is produced by using the molten Al-Si base hyper-eutectic aluminum alloy containing 0.005-0.03% P at 50-150°C excess heating degree to the melting point, while moving during pouring the molten metal near the inner wall of a ladle for supplying the molten metal or near the inner wall of a holding vessel so that the temperature of the molten metal held in the ladle or in the holding vessel becomes uniformity, or while moving this molten metal since the molten metal is poured till it reaches the forming temperature, this molten metal is cooled at 3°C/sec-20°C/sec cooling velocity in the temperature range from the molten metal pouring temperature poured into the ladle or into the holding vessel to a prescribed temperature between the temperature not lower than Al-Si binary-system eutectic temperature and the temperature not higher than the melting point, and thereafter, the semi-solidified metal having the temperature not lower than the binary-system eutectic temperature and a prescribed liquid-phase ratio, is discharged from the holding vessel or the ladle.

摘要： PROBLEM TO BE SOLVED: To provide excellent mechanical properties and a fine metal structure without a shrinkage cavity, which can not be obtained only by a semi-solidified casting method or a semi-solidified forging method (the molding in a semi-solidified state but not the molding in a solid state), by continuously executing the pressurization molding in a state that the solid phase rate is 100 % after a semi-solidified metal is subjected to the pressurization molding without applying a complicated method.
SOLUTION: The semi-solidified metal supplied into a die cavity part is subjected to the pressurization molding with a pair of the upper/lower pressurization molding dies. The upper/lower pressurization molding dies have nearly the same area as the projected area of the upper face or the lower face of a molded product. A second die, which vertically moves in an insertion hole bored in the vertical axis direction, is provided to at least either the upper die or the lower die.
