Abstract

Es wird eine Sphärogusslegierung für Gusseisenprodukte mit einer plastischen Verformbarkeit vorgeschlagen, wobei die Sphärogusslegierung als Nicht-Eisenbestandteile zumindest die Elemente C, Si, Mn, Cu, Mg, S und als Beimengungen eines oder mehrere Elemente aus der Gruppe IIIb des Periodensystems enthält, wobei die Legierung als Beimengung zumindest das Element Bor enthält und wobei der Si-Gehalt mehr als 2,4% beträgt. Es wird auch ein Verfahren zur Herstellung von solchen Gusseisenprodukten mit einer plastischen Verformbarkeit vorgeschlagen, wobei die Nachbehandlung der Oberflächen besonders schonend durchgeführt wird. Die Sphärogusslegierung wird verwendet zur Herstellung eines bruchsicheren, irreversibel und dauerhaft verformbaren Querlenkers.
