... at this low speed will likely result in solidification of the liquid metal before the castings are fully filled. However, because semisolid slurries have 5 to 50% solid particles dispersed in the liquid, their viscosities are higher than those of fully liquid alloys, and at the high end of this solid...

... solidified metal slurry (typically, 50% liquid/50% solid instead of fully liquid metal) is injected into a die cavity to form a die-cast type of component. The origin of SSM can be traced to experiments conducted by David Spencer at Massachusetts Institute of Technology (MIT) in 1971 as part of his...
