Machinability variations in Alloy 718 —With focus on machining of turbine components
In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). The massive cost involved with the machining of nickel alloys has driven continued research and development of cut
