Investigation the effect of molybdenum addition to nickel-chromium alloys

There are several superalloys. Some of them are nickel-based superalloys These alloys have resistance to oxidation,corrosion and wear. Mechanical properties of these superalloys can be improved and used widely by adding some metals.In this study, it was aimed to investigate the effect of molybdenum addition to nickel-based (Ni-Cr) superalloys and to see molybdenum?s effect on physical and mechanical properties (tension and hardness etc. ) of nickel-based (Ni-Cr) superalloys, to observe and participate microscopic structure (SEM, EDAX and XRAY).It was also aimed to develop nickel-based (Ni-Cr) superalloys according to these results. So that these superalloys that have good strenght and resistance to corrosion and oxidation can be used ın biologic medical prosthes materials, tooth prosthes, plane industry and other branches of industry .Key words: Super alloys, nickel based super alloys, Ni-Cr-Mo
