Abstract:Grain refinement of aluminium and its alloys is a common industrial practice. Fine equiaxed, grain structure leads improved castability, strength, machinability, formability, and good surface finish. Filtration is one of the widely used technologies to remove inclusions from the melt. Ceramic Foam Filters (CFFs) are commonly used to clean the aluminium melt before the casting process. However, at a high inclusion load and with grain refiner addition, reduced filtration efficiency is well known to occur. In the… Show more
