Notes:
A simple and efficient rheocasting process that has recently been invented is beingdeveloped for aluminum die casting applications. The process called Gas Induced Semi-Solid (GISS)utilizes the combination of local rapid heat extraction and agitation achieved by the injection of finegas bubbles through a graphite diffuser to create semi-solid slurry. In the GISS process, the die castingmachine and the process cycle remain little changed from those of conventional die casting. The GISSunit creates a low solid fraction of semi-solid slurry in the ladle during the ladle transfer to the shotsleeve. The semi-solid slurry is then poured directly into the shot sleeve. This paper presents thedetailed description of the process. The results of the semi-solid die casting experiments with ADC10alloy using the GISS process are also reported and discussed
