Abstract
The paper evaluates the properties of two cold work tool steels which differ in the production process and content of carbon and vanadium. Both steels are characterized by their great hardenability, toughness, dimensional stability and wear resistance. They are a subledeburitic steel X63CrMoV5-1 produced by classical metallurgy and a ledeburitic steel Vanadis 6 produced by powder metallurgy. Different austenitizing temperatures in the range of recommended values for the material were used during the heat treatment. Both materials were tempered at a temperature of 530 °C. Also cryogenic treatment at temperatures of −196 °C and −180 ° C for 5 h and/or 4 h was inserted into the conventional heat treatment cycle. The effect of the timing of cryogenic treatment in the heat treatment cycle was observed. Hardness measurement, a three-point bending test and a wear resistance test by the pin-on-disk method were used to specify the effect of the conditions of heat treatment on the properties of the investigated materials.
Kurzfassung
Der Beitrag untersucht die Eigenschaften zweier Kaltarbeitsstähle, die sich durch den Herstellprozess und die Gehalte von Kohlenstoff und Vanadium unterscheiden. Beide Stähle zeichnen sich durch ihre große Härte, Zähigkeit, Formbeständigkeit und Verschleißfestigkeit aus. Es sind der subledeburitische Stahl X63CrMoV5-1, hergestellt durch klassische Metallurgie, und der ledeburitische Stahl Vanadis 6, hergestellt durch Pulvermetallurgie. Es wurden verschiedene Austenitisiertemperaturen entsprechend der empfohlenen Werte des Materials während der Wärmebehandlung angewendet. Beide Werkstoffe wurden bei 530 °C vergütet. Es wurde ebenfalls eine Tiefkühlbehandlung bei Temperaturen von −196 °C und −180 ° C für 5 h und/oder 4 h zum konventionellen Wärmebehandlungskreislauf hinzugefügt. Dabei wurde beobachtet, welchen Effekt der Zeitpunkt der Tieftemperaturbehandlung während des Wärmebehandlungszyklus hat. Mit einer Härtemessung, einem Dreipunkt-Biegeversuch und einem Verschleißtest, der Pin-on-Disk-Methode, wurde die Auswirkung der Wärmebehandlungsbedingungen auf die Eigenschaften des untersuchten Materials beschrieben.
