Abstract

Zur Herstellung eines Produkts (1, 15) aus Stahl, bei dem ein Stahl mit einer metastabilen ersten Phase, in der der Stahl erste Eigenschaften aufweist, hergestellt und durch mechanische Einflüsse in eine zweite, thermodynamisch stabilere Phase mit von den ersten Eigenschaften zumindest teilweise verschiedenen zweiten Eigenschaften überführt wird, und zur Anpassung des Produkts an besondere Verwendungszwecke das Produkt (1, 15) lokal unterschiedlich durch Veränderung bezüglich der genannten Phasen mit unterschiedlichen Eigenschaften hergestellt. Ein erfindungsgemäßes Produkt weist daher über seine Oberfläche und/oder seine Dicke wenigstens zwei unterschiedlich eingestellte Bereich (10, 11) mit unterschiedlichen Eigenschaften des Stahls auf.
