Abstract

Przedmiotem zgłoszenia jest sposób obróbki cieplnej średnio- i wysokowęglowej stali stopowej, którego celem jest wytworzenie rozdrobnionej, wielofazowej mikrostruktury składającej się z odpuszczonego ferrytu bainitycznego i martenzytu, poprzedzielanych warstwami stabilnego austenitu resztkowego oraz drobnodyspersyjnych wydzieleń węglików stopowych odpowiedzialnych za twardość wtórną. Sposób ten pozwala na sterowanie udziałem fazowym i morfologią mikrostruktury, umożliwiając osiągnięcie pożądanych właściwości stali pod kątem aplikacji i wymagań stawianych narzędziom i elementom konstrukcji. Sposób może być wykorzystany do kształtowania właściwości elementów, od których wymaga się większej udarności i odporności na pękanie w stosunku do konwencjonalnej obróbki hartowania martenzytycznego i odpuszczania, przy zachowaniu porównywalnej twardości i wytrzymałości. Do elementów tych można zaliczyć m.in. noże przemysłowe, stemple do bicia monet, wykrojniki do tworzyw sztucznych. Obróbka ta pozwala na dłuższą żywotność elementów oraz zwiększa okres bezawaryjnej eksploatacji urządzeń.
