Summary:

UNS N07751 and UNS N07080 alloys are commonly applied forautomotive valve production for high performance internalcombustion engines. These alloys present high hot resistance tomechanical strength, oxidation, corrosion, creep andmicrostructural stability. However, these alloys present low wearresistance and high cost due to the high nickel contents. In thiswork it is presented the development of two new nickel intermediatealloys for application in automotive high performance valves thatare alternatives to the alloys UNS N07751 and UNS N07080.The new developed alloys are based on a high nickel chromiumaustenitic matrix with dispersion of γ' and γ'' phasesand containing different NbC contents. Due to the nickel contentreduction in the developed alloys in comparison with the currentused alloys, the new alloys present an economical advantage forsubstitution of these traditional Ni-based alloys, once the newalloys present similar to better properties than UNS N07751 and UNSN07080 alloys
