Microstructure and Mechanical Properties of Squeeze Cast Semi-Solid Materials

Abstract:

Several rheocasting processes have been developed or applied in the world. One of the new rheocasting processes is the limited angular oscillation (LAO), in which the molten metal is rapidly cooled and slightly mixed during initial stages of solidification. Squeeze casting (SQC) using semi-solid slurry produced by LAO (Rheo-SQC) has been developed. Microstructure and mechanical properties of squeeze cast semi-solid slurries have been investigated. Complete parts with little defects have been produced. The ultimate tensile strength and elongation of semi-solid cast samples are higher than those of the liquid cast samples. It can be concluded that the rheo-SQC is a feasible process.
