Abstract

Der erfindungsgemässe Leichtbaustahl wird aus einem mehrphasigen Gefüge im Falle eines Duplex-Stahls aus α-Ferrit- und η-Austenitmischkristallen gebildet. Im Falle des Triplexstahls tritt zu den beiden erstgenannten Phasen noch eine martensitische ε-Phase und/oder λ-Phase hinzu. Das spezifische Gewicht des erfindungsgemässen Stahls wird durch die hohen Anteile von leichten Legierungselementen Al, Si, Mn, Mg, Ga und Be auf niedridge Werte abgesenkt. Mit den erfindungsgemässen Legierungen wird eine Dichte unter 7 g/cm3 erzielt.
