what is mean by Semi solid slurry??
Semisolid forming has held much promise for a number of years but to date has not significantly penetrated commercial production of castings. This lack of take-up is mainly driven by the extra cost of adding a processing step to establish a semisolid slurry of the appropriate solid phase morphology and size. However, semisolid processing has found a niche for castings requiring consistent quality with a very low defect structure and it remains an effective method of reducing grain size with or without the addition of grain refiner particles.
