アルミニウムとニッケルの混合粉末を用いた半溶融ダイカスト Experimental Study of Semi-Solid Die Casting Using Mixture of Elemental Alminum and Nickel Powders
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 Al<sub>3</sub>Ni particles, primary Al<sub>3</sub>Ni 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 Al<sub>3</sub>Ni 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.
