Abstract
High strength and high ductility together are prime requirements for modern structural metallic materials. Important industrial examples are steels for car components such as body sheets, tubes and forgings. The present paper traces two lines of alloy development, stable austenitic stainless steels and intentionally metastable austenitic stainless steels. Although both groups have different advantages and disadvantages, each one exceeds all other presently available structural metallic materials in terms of strength to density ratio at equal ductility.
Abstract
Die Legierungsentwicklung stabiler und metastabiler austenitisch rostfreier Stähle wird vergleichend dargestellt. Beide Gruppen von Stählen haben unterschiedliche Vorzüge und Nachteile, aber jede Gruppe übertrifft alle anderen heute verfügbaren metallischen Strukturwerkstoffe in Bezug auf das Festigkeit-zu-Dichte Verhältnis bei gegebener Verformbarkeit. Mögliche Anwendungsbereiche schließen die Automobilindustrie mit ein.
