Abstract
Al-Ti-B grain refiners are used by aluminum alloy casting manufacturers to reduce the grain size of castings. Both Al-5Ti-1B and Al-3Ti-1B are common Al-Ti-B grain refiners that are produced by several grain refiner manufacturers. The grain refining effectiveness with respect to time of four Al-5Ti-1B refiner samples from four grain refiner manufacturers and two Al-3Ti-1B refiner samples from two manufacturers was tested on commercial purity aluminum. Among the same type of grain refiners, the result of comparing grain refining efficiency from different grain refiner makers has been discussed in this paper. The composite particles of the grain refiner samples were observed by SEM and analyzed in an attempt to approach and understand the result of grain refinement under stirring.
