... and the advantages claimed for semisolid casting. It describes the four notable processes used to produce semisolid castings: thixocasting, rheocasting, thixomolding, and wrought processes. Most commercial aluminum semisolid casters use either thixocasting or rheocasting. The article discusses the die design...

... die casting and its derivatives processes, such as semisolid metalcasting (thixocasting), slurry-on-demand (rheocasting), and squeeze casting. Fluidity in die casting is somewhat lower than Silafont-36 (alloy 365.0), due to its lower silicon content. However, the tendency for shrinkage formation...

Stirring at high speeds creates a high shear rate, which tends to reduce the viscosity of the slurry even at solid fractions as high as 50 to 60% volume. The process of casting such a slurry is called rheocasting . The slurry can also be mixed with particulates...
