Abstract:
This paper presents the effects of Niobium additions (1, 2 and 3%) on the wear resistance and impact properties of Hadfield steels (1.2%C and 12-18%Mn). The additions of Nb promoted a significant decrease in the mass losses, from 79 mg (Hadfield steel with 12%Mn) to 33 mg (Hadfield steel with 3%Nb) in the abrasive wear test (rubber wheel); and from 29 mg (Hadfield steel with 12%Mn) to 24 mg (Hadfield steel with 1%Nb) in the friction wear test (pin on disc). The results showed a reduction in the energy absorbed in the impact tests proportional to the Nb content (from 200J in the standard Hadfield steel to 53J with addition of 2%Nb). Keywords: Hadfield steel; niobium addition; abrasive wear; friction wear; impact energy.
