Abstract
The filtration of a melt is known to be an efficient method for decreasing the amount of nonmetallic inclusions. Ceramic foam filters are applied for the filtration refining of an EP-648-VI alloy. Comparative results of experimental melts using ceramic foam filters and melts carried out using a traditional technology show a decrease in dissolved gases and the improvement of the mechanical properties of the EP-648-VI nickel alloy.
