Abstract
As production of compacted-graphite irons (CG irons) has continued to rise, the use of denodularising (antispheroidising) elements (Ti, Al, Sb, Sn, etc) has led to the build-up of these deleterious elements in the compacted graphite cast iron returns (CG returns). Can this be a problem for the future of nodular and compacted graphite irons production? Can these two types of cast irons be produced in the same foundry? These are the questions this paper tries to answer.
