The Effect of Al-5Ti-1B and Combination Electromagnetic Field on Grain Evolution of Die Casting Commercial Aluminum

Abstract

The effect of increasing the amount of added grain refiner and combination electromagnetic filed on grain size and morphology has been investigated by die casting of commercial aluminum. The results show the grain size and the grain morphology both are transited with the increasing of the addition of Al-5Ti-B. The grain size continuously decreased with increasing the addition of grain refiner. Without grain refiner additions, an obvious transition in grain size and morphology is observed with the application of low frequency electromagnetic field (LFES). The efficiency in grain refinement of LFES decreases with increasing the amount of grain refiner. However, even when the addition of grain refiner is 2 wt. % Al-5Ti-B, 63 % grain size reduction still is observed by the affect of LFES. This result shows that the LFES can enhance the efficiency in grain refinement of grain refiner.

Review of measures for improved energy efficiency in production-related processes in the aluminium industry – From electrolysis to recycling

“…However, electromagnetic casting can be used for die casting as well (see e.g. [132] and [133]), so CRIMSON casting and electromagnetic casting can possibly complement each other. Some of the other measures can be combined, since they affect different parts of the casting operations.…”
