Effect of Solid Lubricant on Machinability of Inconel 718

Inconel 718 is one of the Heat Resistant Super Alloy (HRSA) from nickel-chromium group suitable for aerospace applications Inconel 718 is used in hot sections of gas turbines, rocket engines (including the space shuttle main engine), spacecraft structural components, nuclear reactors, pumps, tooling, in the manufacture of components for aircraft turbine engines, cryogenic tankage and nuclear industries . Inconel is considered as one the difficult to cut metal and to find out causes of why Inconel 718 is difficult to machine is a topic of research for many researcher since past many years Solid lubricant assisted machining is an environmental clean technology in which solid lubricants in form of powder or paste is during machining instead of conventional flood cooling
