Aluminum high pressure castings (HPDC) were successfully produced on two simple but slightly different H13 steel dies that had been coated with AlCrN physical vapor deposition (PVD) coatings and without the use of conventionally-sprayed die lubricant

AlCrN-type PVD coatings are excellent candidates for die coatings; they reduce or eliminate the need for conventional lubricants in aluminum die casting. A variety of AlCrN-based coatings are commercially available, and an understanding of their diff

Porosity is one of the main defects that limits the performance of castings. Porosity in aluminum castings can originate from several sources, including the volumetric shrinkage occurring during solidification, the precipitation of dissolved hydrogen

The SEED (Swirled Enthalpy Equilibrium Device) process was used to produce semi-solid slurries. One of the factors that controls whether or not a slug can be used to produce high quality castings is the solid fraction distribution within the slug, an

Semi-solid aluminum slurries have globular grains, different from traditional dendritic solidification microstructures. The mechanism responsible for the formation of these globular grains is still in dispute. Some researchers suggest that the globul
