dc.description.abstract© 2015, Associazione Italiana di Metallurgia. All rights reserved.It is well known that austempering produces a bainitic microstructure bainitic and is the preferred heat treatment when toughness is the main requirement of the component. Literature reports several works where mechanical properties for tempered martensite and bainite exhibits the same hardness and that better properties are obtained for the bainitic microstructure. The impact properties of O1 alloy steels (high carbon tool steel) subjected to different heat treatment cycles is reported here. Tempered martensite was obtained from conventional heat treatment, with or without subsequent cryogenic treatment bath are compared with the bainitic structure produced in austempering. Austempering was performed at 350°C and soaking times were: 20 minutes, 40 minutes and 60 minutes. Since hardness influences impact behavior, comparative studies were performed at the same surface hardness level. Results have shown low absorbed energy for austempered samples which are independent of the soaking time at the austempering temperature.
