..., spheroidal solids floating in the liquid. 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...

... With an understanding of semisolid metal behavior, several new net-shape manufacturing processes were developed based on closed-die forging, die casting, extrusions, rolling, and hybrids of these processes ( Ref 1 , 2 , 3 ). Since its conception, semisolid metalworking has been applied to numerous metal alloy systems...

... had its genesis in Merton Flemings' lab in 1971 with the rheological experiments done by David Spencer as part of his doctoral thesis. The discovery that shearing a semimolten metal produced potentially castable rheologies ignited tremendous interest in what would be an entirely new area of casting...

..., on the contrary, high-pressure die casting makes it possible to obtain very fine microstructures. Semisolid techniques (e.g., rheocasting, thixocasting, etc.), on the other hand, even though less widespread, allow the production of casting components with very low defect contents.
