Abstract
Thick-walled parts made via a casting method often exhibit, in those thick zones, the worst mechanical properties since the solidification speed in the zones is reduced relative to the thin-walled zone and frequently induces the worst mechanical properties. There is described a method incorporating solidification control elements in a melting charge, the elements increase locally the solidification speed of the melting charge.
