抄録

  The effects of mechanical stirring on the semi-solid state of Al-20mass%Ni alloy prepared from elemental powders were examined to obtain information on the semi-solid die casting method using the powder. The structure of the specimen made from unstirred slurry with 15% solid fraction consists of Al3Ni particles, primary Al3Ni phase and eutectic, but a large amount of cored structures containing nickel particles as nucleus was observed for slurry with 38% solid fraction. Stirring the slurry was found to be effective for bringing it to an equilibrium condition of slurry. The Al3Ni particle in the products was found to disperse uniformly when the slurry was stirred. The particle size also increased when the solid fraction of slurry was high.
